Why Choose ZEL Compressors?

ZEL compressors are renowned for their reliability, energy efficiency, and versatility. Here are some key reasons to consider them:

• Reliability: Engineered for long-term performance in demanding conditions.
• Energy Efficiency: Optimized for minimal energy consumption with high COP values.
• Versatility: Suitable for both small domestic units and large industrial systems.

 

1. Compressor (Model S36G)

• 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

1. Compatibility: Ensure the compressor (S36G) is designed for R134a and water-cooled operation.
2. Refrigerant Charge: Confirm 32g is correct (undercharging/overcharging affects performance).
3. Water Cooling: Check for scale buildup, water flow rate, and pump functionality.
4. 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.

▷ Starting and Running Capacitors Table

Do you need to replace a start or run  capacitor   and you don’t know which one the equipment has? In this post we will give you some tables of start and run capacitors so that you can access it when you need it.

The topic regarding the calculation of capacitors for single-phase compressors  is of great importance, because whoever is repairing needs to know when it is in poor condition and also what the replacement of the damaged part will be.

The technician who manipulates the equipment has to know that the new capacitor that he has bought to replace the old one must exactly meet the working voltage or greater than that of the original.

It is also important to highlight in this article that the compressor voltage has almost no relation to the capacitor voltage.

If you do not have the original capacitor data, you can approximate it using the following capacitor values ​​for single-phase motors that we present below.

They can be used as a guide or reference for selecting,  replacing capacitors when the exact values ​​are unknown.

Understanding Starting Capacitors for Compressors: A Comprehensive Guide

Introduction
Starting capacitors play a crucial role in the efficient operation of compressors, especially in single-phase motors. They help generate the necessary starting torque and ensure smooth operation. This guide provides a detailed overview of starting capacitors, their importance, and how to select the right one for your compressor. We’ll also explore key specifications and troubleshooting tips to ensure optimal performance.

1. What is a Starting Capacitor?

A starting capacitor is an electrical component used in single-phase motors to create a phase shift, which generates the torque needed to start the motor. Without a starting capacitor, single-phase motors would struggle to start due to insufficient torque.

---

2. Key Functions of Starting Capacitors

• Generate Starting Torque: Provides the necessary torque to start the compressor motor.
• Phase Shift Creation: Creates a 90-degree phase shift to simulate a second phase in single-phase motors.
• Smooth Operation: Ensures the motor starts smoothly without excessive current draw.

4. How to Calculate the Right Capacitor for Your Compressor

The capacitance of a starting capacitor is critical for optimal performance. Here’s a simple formula to calculate the required capacitance:

Formula:

C=P×1062πfV2cos⁡(ϕ)C=2πfV2cos(ϕ)P×106​

Where:

• CC = Capacitance (in microfarads, µF)
• PP = Motor power (in watts, W)
• ff = Frequency (in hertz, Hz, typically 50 or 60 Hz)
• VV = Voltage (in volts, V)
• cos⁡(ϕ)cos(ϕ) = Power factor (typically 0.85 for motors)

Example Calculation:
For a motor with:

• Power (PP) = 150 W
• Voltage (VV) = 230 V
• Frequency (ff) = 50 Hz
• Power factor (cos⁡(ϕ)cos(ϕ)) = 0.85

C=150×1062π50×2302×0.85≈10.61 μFC=2π×50×2302×0.85150×106​≈10.61μF

• Relay:

  • The relay is used to provide additional electrical current to the start terminal (S) of the compressor, helping it start smoothly.

• Capacitor:

  • The capacitor improves the compressor’s torque during startup, reducing the load on the electric motor.

• Electrical Circuit Diagram:

  • The diagram shows how the compressor terminals (C, S, R) are connected to the relay, capacitor, and power source.

---

2. Compressor Terminal Connections

• C (Common):

  • The common terminal connected to both the run and start windings.

• R (Run):

  • The terminal responsible for continuous operation of the compressor after startup.

• S (Start):

  • The terminal responsible for starting the compressor with the help of the relay and capacitor.

---

3. Steps to Connect the Relay to the Compressor

A. Connecting the Capacitor:

• The capacitor is connected between the S (Start) terminal and the R (Run) terminal to support startup torque.

B. Connecting the Relay:

• Terminals 10 and 11:

C. Power Supply:

• The circuit is powered by a 110V or 220V source (depending on the system used).

---

4. How the Relay Works

• When power is connected, the relay sends additional current to the start terminal (S) via the capacitor.
• Once the compressor starts running, the relay automatically cuts off the current to the start terminal.
• The compressor continues to operate through the current flowing to the run terminal (R).

---
