Chapter 18, Problem 5RQ

What is the primary purpose of a thermostat jiggle valve? Select one: a. To act as a bypass for coolant b. To relieve water pump pressure under load c. To ensure coolant flows the correct direction d. To aid in bleeding air from the system

Which of the following statements is false?     The condenser is normally mounted just in front of the radiator.     The receiver/dryer is a storage tank for the liquid refrigerant from the condenser.     An accumulator is not used in any system with a receiver/dryer.     All of the above.

to run d. both a and b 44. Ifa thermostatic expansion valve's thermal bulb came loose from the suction line at the outlet of the evaporator, whích of the following could result? The bulb pressure would increase and the c. thermostatic expansion valve would open. b. The superheat in the evaporator would decrease. a. Liquid refrigerant would flow back to the compressor. d. All of the above are correct. 45. If the thermal bulb assembly develops a leak, what will occur? All of the system's refrigerant will leak a. The valve will open to allow more c. refrigerant to flow. d. It will have no effect on system operation. out. b. The bulb pressure will reduce and the valve will close. 46. The purpose of an externally equalized thermostatic expansion valve is to compensate for excessive evaporator pressure drop b. allow system to equalize faster a. prevent the expansion valve from frosting up d. c. allow refrigerant to expand in the compressor 47. The primary function of an expansion device is…
