The Amana-Goodman 0130F00041 -0.90” PF SPST Pressure Switch is an essential part of many HVAC applications including furnaces and air conditioners. This particular switch is used in controlling pressure within the system and; therefore, it is well developed. It operates on a simple yet effective principle when the air pressure is set at a certain level, normally -0.90 inches of water column , the switch turns on or off the required parts. This precise control allows achieving the highest performance of the system and its safety. The pressure switch ensures that pressure build up or vacuum conditions are not allowed to go high or low respectively ensuring correct airflow, combustion and heat exchange.
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 ...
