The Carrier HK42FZ035 Circuit Board Less Plug is a replacement part for Carrier HVAC systems. It functions as the system's brain, interpreting signals from various components to regulate essential functions like heating, cooling, and airflow. This ensures your HVAC system maintains a comfortable temperature in your home. The circuit board is made from FR-4 flame-retardant material for safety and durability. It operates within a wide temperature range of -40°C to 85°C, allowing it to function effectively in various environments. The board measures 6 inches by 4 inches with a thin profile of 1.6 millimeters, making it easy to integrate into existing HVAC systems. This circuit board is sold without a plug for electrical safety; proper installation by a qualified technician is recommended.
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 ...
