Heat added to the refrigerant in a vapor state after the evaporation process is called; 🗸🗸🗸 : Superheat. A scroll compressor move refrigerant by means of; 🗸🗸🗸 : Involute Spirals. The movement of heat by way of fluid (or air) is called; 🗸🗸🗸 : Convection. The movement of heat by direct contact is called; 🗸🗸🗸 : Conduction. 2 | P a g e The standard unit for measuring the quantity of heat in a substance is; 🗸🗸🗸 : The British Thermal Unit (Btu). A refrigerant gives up heat when; 🗸🗸🗸 : It condenses. Why must refrigerant in the suction line be slightly warmer than the saturation temperature? 🗸🗸🗸 : Prevent liquid slugging of the compressor. The state of the refrigerant in the suction line should be; 🗸🗸🗸 : Low pressure/low temperature vapor. The state of refrigerant entering the condenser is; 🗸🗸🗸 : High pressure/highly superheated vapor. The evaporator; 🗸🗸🗸 : Transfers heat from the refrigerated space to the refrigerant. Which of the following is not a thermodynamic property of refrigerants? 🗸🗸🗸 : Enthalpy. 3 | P a g e The sequential order of the steps in the vapor - compression processes are; 🗸🗸🗸 : Compression, condensation, expansion, vaporization. If a 30 pound cylinder of reclaimed R -410A refrigerant has been stored overnight at 70°F, the pressure in the cylinder should be approximately; 🗸🗸🗸 : 201 psig. Fan airflow pressures are usually measured in; 🗸🗸🗸 : Inches of water column (WC). Zero p sia (pounds per square inch absolute) is; 🗸🗸🗸 : A pressure which cannot be further reduced. Zero psig (pounds per square inch gauge) is; 🗸🗸🗸 : The same as the atmospheric pressure. The temperature at which moisture will start to condense from the a ir is called; 🗸🗸🗸 : Dew point temperature. A compound pressure gauge measures; 🗸🗸🗸 : Pressure and vacuum.
