The York S1-024-25808-702 Pressure Switch is one of the safety devices that regulate pressures in heating and cooling systems. This pressure switch has a pressure of -0.60” of WC and is wired as a single pole, single throw. This measures pressure in the system and turns on or off HVAC equipment depending on pressure set points. The switch is also small and measures 5.8 x 3.1 x 3” meaning that it can be easily installed in most HVAC systems. The benefits of this pressure switch are that it will guard the system against pressure related issues, it will prevent equipment failure by making sure that there is enough pressure and that the reliability of the system is enhanced.
How to install an expansion valve for refrigeration?
Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.
These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.
Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...
