The Lennox 69W52 Blower-Wheel is an essential part of residential heating, ventilation and air conditioning systems including air handlers and furnaces. This is a directly driven fan wheel with 48 blades and rotates in the clockwise direction to blow air internally within the unit. The wheel has a diameter of 10" and width of 9" with convex hub and bore diameter of ½ Inch for direct coupling to the motor shaft. This blower wheel BTW is a component critical to the proper functioning of your HVAC system. By air through the system’s filters and heat exchanger or evaporator coil, the blower wheel provides proper circulation of conditioned air for your entire house.
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 ...
