Purpose: The core component for pressurizing refrigerant in a cooling cycle.
Model S36G: Likely a specific compressor model (possibly from a brand like Secop, Danfoss, or a regional manufacturer). Verify with manufacturer documentation for exact specs.
Application: Small-scale systems (e.g., commercial water coolers, medical devices, or compact refrigeration) due to the small refrigerant charge.
2. Refrigerant (R134a, 32g)
R134a: A common hydrofluorocarbon (HFC) refrigerant used in medium-temperature systems (e.g., refrigerators, AC units, water coolers).
32g Charge: Indicates a small system, typical for portable or compact units. Ensure the charge matches manufacturer specifications to avoid inefficiency or damage.
3. Water-Cooler System
Water-Cooled Condenser: Uses water (instead of air) to dissipate heat, improving efficiency. Requires a water supply, pump, and possibly a cooling tower.
Applications: Often found in commercial settings (e.g., water dispensers, industrial chillers, or high-efficiency HVAC systems).
4. BLY-F/950
Likely a component model, such as:
Filter drier: Removes moisture/contaminants from refrigerant.
Pressure switch: Safety device to control system pressure.
Control board/Valve: Part of the system’s electrical or flow regulation.
Check manufacturer manuals or suppliers for exact function.
Key Considerations
Compatibility: Ensure the compressor (S36G) is designed for R134a and water-cooled operation.
Refrigerant Charge: Confirm 32g is correct (undercharging/overcharging affects performance).
Water Cooling: Check for scale buildup, water flow rate, and pump functionality.
BLY-F/950 Replacement: Cross-reference with OEM parts or contact the system manufacturer.
Troubleshooting Tips
Low Cooling Efficiency: Check refrigerant charge, water flow, or condenser cleanliness.
Component Failure: Test the BLY-F/950 part (e.g., continuity for switches, clogging in filter driers).
Noise/Leaks: Inspect the compressor and refrierant lines.

Sistemas de arranque:
En el caso del relé de arranque, cuando la energía es aplicada al compresor, la bobina solenoide del relé atrae la armadura del mismo para arriba produciendo el cierre de los contactos, energizando la bobina de arranque del motor. Cuando el motor del compresor alcanza la velocidad de funcionamiento, la corriente de la bobina principal del motor será tal que la bobina solenoide del relé desenergiza permitiendo que los contactos del relé se abran, desconectando de esta manera la bobina de arranque del motor.
The PTC is a semiconductor with a positive temperature coefficient, which means that it offers no resistance to the passage of current when the unit is cold. When the unit is turned on, the current passing through the PTC causes it to heat up rapidly, creating such a high resistance in its circuit that the passage of current remains at a very low value but high enough to keep the PTC warm.
Prerequisites for using the PTC system:
– The thermostat must be used to ensure that the stop time allows for pressure equalisation in the system. – Depending on the size of the compressor, the stop period should be at least 3 to 5 minutes (e.g. the minimum times for TL are 3 minutes, and for SC 5 minutes).
The PTC system offers a number of advantages:
– Improved protection of the starter coil – PTC is not affected by voltage increases or decreases – Free from radio and television interference – No wear – Identical PTC starter system for many compressors of different sizes.
LST (low starting torque) engines
Compressors with RSIR and RSCR system motors have a low starting torque (LST) and are used in refrigeration appliances with capillary tubes, where pressure equalization takes place before each start.
The RSIR system incorporates a PTC thermistor or a relay and a bifilar winding (current relay) as starting equipment. The PTC needs to be kept off for a period of about 5 minutes to allow it to cool down before it can restart.
RSCR (Resistant Start Capacitor Run): Induction motor with resistor start and run capacitor.
The RSCR system, consisting of a PTC thermistor and a run capacitor, is mainly used in energy-optimized compressors.
HST (High Starting Torque) Engines
Compressors with CSIR and CSR type motors have a high starting torque (HST) and can be used in refrigeration appliances with capillary tubes as well as in systems with expansion valve operation (without pressure equalization).
– CSR (Capacitor Start Run): Induction motor with start capacitor and run capacitor
CRS systems require a voltage relay, a start capacitor and a run capacitor.
– CSIR (Capacitor Start Induction Run): Induction motor with starting capacitor.
The CSIR system consists of the starting relay and starting capacitor specified for each particular compressor type.
Graphic summary:
Conditions for a long service life
To achieve trouble-free operation and long service life of the hermetic compressor, the following conditions must be met:
1. The starting torque must be sufficient to enable the motor to start under the prevailing pressure conditions in the system. 2. The maximum torque of the motor must be sufficient to enable the motor to withstand the load conditions at start-up and during running. 3. During operation of the refrigeration system, the temperature of the compressor must never rise to levels that could damage its components. Condensation and compression temperatures must therefore be kept as low as possible. 4. Correct sizing of the refrigeration system in question, and a correct assessment of the operating conditions of the compressor under maximum loads. 5. Sufficient cleanliness and minimum residual moisture in the system.
Engine overload
The motor start-up is determined by the starting torque and/or the maximum torque of the motor. If the starting torque or the maximum torque are insufficient, the compressor cannot start or the start-up will be hindered and delayed due to the activation of the internal motor protector.
Repeated starting attempts subject the motor to overload, which will sooner or later result in failure. It is all a matter of selecting the right compressor for extreme working conditions.
Thermal overload
To ensure a long compressor life, operating conditions that lead to thermal decomposition of the materials used in the compressor must be avoided. The materials involved are coolant, oil and materials for motor insulation. Motor insulation consists of enamel for the copper winding, insulation for the stator core slot, insulating tape and power cables.
The R 134a, R 404A or R 507 refrigerants used today require advanced oils. Only special quality POE oils (polyester) are used.
For the application of compressors in domestic and commercial refrigeration devices with the refrigerants that are currently available, it is advisable to comply with the following rules.
Coil temperature
The coil temperature must never exceed 125°C during continuous operation. For limited periods of time, e.g. during compressor start-up or in case of short load peaks, the temperature should not exceed 135°C.
For commercial refrigeration with R 134a, the same values apply as for domestic refrigeration. However, cooling the compressor by means of a fan is recommended.
Condensation temperature
When using R 600a or R 134a refrigerants, the condensation temperature during continuous operation must not exceed 60°C. During short load peaks, the temperature must not exceed 70°C.
In commercial refrigeration where R 404A and R 507 refrigerants are used, the condensation temperature limit is 48°C during continuous operation and 58°C during peak loads.
Checking the compressor coils.
We must take into account that we are going to check an electromechanical part since it has an electrical part that makes another mechanical part work and it is necessary to carry out several types of tests to be able to determine if it is damaged and if it is possible to find out which part of the compressor is damaged. For these tests we will need measuring tools and a little expertise since in some we will use the senses, we will divide the tests into two parts, one when it is installed and the other when the compressor is alone without being installed.
Measure continuity between the compressor coils:
For this test we will need a tester that measures continuity, we will have to disconnect the compressor cables, the test consists of verifying that there is continuity between the compressor terminals and measuring two by two we verify if there is no continuity in these terminals, we must take into account the temperature of the compressor, if it is cold the coil is open (damaged), if the compressor is hot we must wait for it to cool down because it may be that the thermal switch is open due to high temperature and we perform the test again.
If you are disconnected or off the computer, this test is performed in the same way.
Test if the amperage is too high:
For this test we will need a clamp meter and we will place it in one of the compressor lines, either the common one, preferably the start (maintenance) line, it should not be placed on the start-up line because it will not give us the measurement we need to check, we must know the normal working amperage of the compressor, start it, wait for it to stabilize, at start-up it normally consumes 5 times the working amperage, we wait for it to stabilize and if it is above that indicated on the plate it is too high in amperage, in this case we will have to check, capacitor, ventilation, pressures, voltage tension, to determine if it is because of the compressor or an external cause. If the compressor is disconnected from the equipment and the amperage exceeds that indicated it is a sign that it is damaged and we should not install it.
Determine if compressor pumps well:
Pressure test: it is not advisable to measure the output pressure, however there are technicians who when buying a used compressor usually measure the high pressure, if it exceeds 300 psi the compressor is fine and if when turning it off the pressure is maintained without it returning, it is an excellent sign that everything is fine, it is not low on compression since the valves do not return pressure, this test is not performed on rotary compressors because they work with the pressure and temperature of the same compressor to reach the normal working refrigerant gas pressure.
If the compressor is installed when measuring with the pressure gauge and registering that the high pressure does not rise and the low pressure is very high, it is a sign of decompression. If it is a rotary equipment, we look at the suction filter that is located at the compressor inlet to see if it freezes. If it is frozen it is due to obstruction. If, upon observing this, everything is normal, it is most likely that the pressures are destabilized due to low compression. Another sign is that the amperage with the low pressure high and the high pressure low will show a consumption well below normal since it is not exerting force to maintain a high pressure in the condenser.
Determine if the compressor is seized:
For this we need to use the ammeter or clamp meter when trying to start the having a suitable capacitor and in good condition it should not exceed the starting amperage which is 5 times the nominal or working amperage, if it exceeds it is a sign that it is blocked, we can use an additional starting aid to the capacitor and if with this the result is the same (taking into account that the voltage is normal) we will determine that the compressor is seized and it is necessary to replace it.
When I mention at the beginning that we should use our senses, I mean that if we are testing a compressor and we notice a strange noise when starting it, this is not a good sign, and if it is already in full operation and sounds unusual, it is a bad sign, as well as looking at the part where the cables are connected to the compressor, since this is a seal that sometimes gets damaged and allows oil to leak, be attentive and verify that the filter that is fixed by a belt in the case of rotary compressors is not subject to this belt being damaged, since it also produces noise, refrigerant gas leaks and vibrations, these are details that we should be very attentive to.
Note: We should always try to exhaust every last resource to determine if a compressor is damaged, because if we are technicians and they seek a second opinion, and it works in the hands of the second opinion, the client will think the worst of us and our reputation will be in jeopardy, and if the compressor is our property, we should also exhaust all resources, since it is the most expensive part of our air conditioning, both its individual price and the expenses generated in labor and materials for its installation. We must be very clear that it no longer works for ourselves and for others.
Checking the starting capacitor.
To test a starting capacitor in a simple way, we simply connect it in series with an incandescent light bulb and supply it with AC voltage. We will also complement the assembly with a normally open push button like the one used in doorbells, which we will connect in parallel with the capacitor according to the following diagram.
Calculation of the starting capacitor capacity:
Many refrigeration compressors are single-phase motors. The problem with supplying a motor with 230 V, with a single phase, means that the torque needed for starting is not generated. To “trick” the motor and generate a fictitious phase, a capacitor is used that shifts the supply voltage by 90º. In this way, we will have the necessary starting torque. To obtain the best and most powerful starting torque of the single-phase motor, which will result in the refrigeration compressor working better and with more force and not jamming… the capacity of the capacitor that obtains this 90º phase shift must be calculated.
It is not true that the larger the capacitor, the greater the starting torque of the single-phase motor. The only thing that is obtained is a greater phase shift, which will produce a lower starting torque of the single-phase motor. In fact, if the capacitor is too large, it may happen that the phase shift is 360º, that is, 0º, so that the single-phase motor would have no starting torque. In any case, capacitors with a higher or lower capacity than necessary will generate phase shifts lower or higher than the optimum, which will result in starting torque values lower than the optimum. Starting with starting torque lower than the optimum can result in our single-phase motor burning out; it has to make more effort than necessary to start, the intensity increases and the motor burns out, which would end up being damaged.
The highest starting torque for the single-phase motor is obtained when the phase shift we obtain with our capacitor is 90º. To obtain this phase shift we will proceed to calculate the capacitor of a single-phase motor in the following way.
Suppose we have an engine with the following characteristics
Power 150 W Working voltage 230 V. Frequency 50 Hz. Cosine of phi = 0.85
Applying the formula, the capacitance is 10.61 microfarads.
Therefore, the optimal ideal capacitor for the single-phase motor in the example is 10.61 uF, as 10.61 micro Farads is a capacitor value that we cannot find on the market, we will choose to buy the value that is closest in this case 10 micro Farads.
