(RH) 4 Temperature 2 KEY TERMS After studying this chapter, the reader should be able to: 1 State: Kansas The evaporation chamber completely separates the gas-liquid two phases That’s the basic principle you have to work with in duct design while larger systems work The expansion valve is designed so that the temperature of the refrigerant at the evaporator outlet must have 8 to 12°F (4 to 7°C) of superheat before more refrigerant is allowed to enter the evaporator The evaporator is mainly composed of two parts: the heating chamber and the evaporating chamber As this refrigerant enters, it suddenly finds itself able to spread out in the relatively empty evaporator coil 4kW, and LD20A24AB 24 volt and DC 72V Compressor are also available The required internal chemicals plus air needed is supplied from the atmosphere Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house By cooling the air in the passengers compartment, humidity is also lowered for improved passenger comfort Electrostatic air filter devices do work fairly well to filter allergens from the air, because they filter particles like dust, pet dander, or mold, which are the usual suspects when it comes to allergies 20) Air enters a large duct at the front of the car, placed so that when the car is moving the entry point is in a high-pressure area and air is forced in As a result, roughly 117 million metric tons of carbon dioxide are released into the air each year The refrigeration cycle is the main
