Irrigation Solenoid Valves: Common Faults, Causes and Troubleshooting

Generally, before diagnosing the problem of irrigation solenoid valves (sprinkler solenoid valves), some work needs to be done: such as determining whether the water source is turned on, whether the controller is connected to the power supply and the program setting is correct, whether the flow control handle on the solenoid valve is closed, and then try operating the valve manually.

Refrigeration, Air Conditioning Compressors: Reciprocating, Rotary, Screw, Centrifugal, Scroll

What is Refrigeration Compressor The compressors are one of the most important parts of the refrigeration cycle. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. It then moves to the expansion valve, and the evaporator and it is finally sucked by the compressor again. For the proper functioning of the refrigeration cycle, the refrigerant must be compressed to the pressure corresponding to the saturation temperature higher than the temperature of the naturally available air or water. It is the crucial function that is performed by the compressor. Compression of the refrigerant to the suitable pressure ensures its proper condensation and circulation throughout the cycle. The capacity of the refrigeration or air conditioning depends entirely on the capacity of the compressor.<img src="{{media url=&quot;422C8FF7C729C6E9A7416FCA7C2EB508849153E1_large.jpg&quot;}}" alt="" />

Hitachi heat pump compressor

Does the compressor not start related to the four-way valve? There is no relationship between the compressor does not start and the four-way valve. Therefore, when the four-way valve coil is damaged, it will not cause the air-conditioning compressor to fail to start normally, nor will the compressor start normally after the good four-way valve coil is replaced.
