ESCO Light Commercial Refrigeration EXAM 100% VERIFIED ANSWERS 2024/2025 CORRECT In a dry type (direct expansion) evaporator, liquid refrigerant must boil away as close to the end of the coil as possible in order to: The difference between the temperature of the refrigerant boiling in the evaporator and the temperature at theevaporator outlet is known as: An expansion device that is stuck open will cause: When measuring evaporator superheat on a commercial system that has a long suction line, the pressure reading should be taken at the: Superheat measurements are best taken: Atechnician is checking the superheat on a multi-circuit evaporator and finds one of the circuits has a superheat that is higher than the others. This could be caused by: A TEV with an external equalizer is used on: Dry type evaporators operate most efficiently with a superheat setting of approximately: An evaporator used to chill liquids si operating with a normal superheat setting, but the system is not cooling the product properly. Which of the following is the most likely cause? What time interval is required between each superheat adjustment? Alow temperature evaporator used for cooling space or product refrigeration: Some special applications use aflooded evaporator (operated full of refrigerant). nI order to maintain the proper level of liquid refrigerant, a type metering device is used. A properly functioning condenser will first; The effect of an inefficient water cooled condenser will; The refrigerant condensing temperature in a water cooled condenser is normally about higher than the leaving water. The refrigerant in an air cooled condenser will normally condense at approximately higher temperature than the air passing over it. Workable head pressure during periods of lowambient temperature can be achieved by using; Cooling towers that pass air over water to remove system heat are limited in capacity by: Parallel compressors often referred to as a rack system may use; The major difference between a cooling tower and an evaporative condenser is: Multiple compressors provide: Adirty evaporator and subsequent low evaporator pressures will cause: he thermostatic expansion valve (TV) maintains a constant__________ in the evaporator. What type of ice si made with a commercial cie maker that uses a gear motor and auger? Some capillary tube systems take advantage of heat exchange by soldering the capillary tube to the suction line. In order to obtain the correct superheat reading, it must be taken: A_____________is usually required for ultra-low temperature applications. A hot gas defrost cycle can be initiated by a: When the defrost cycle is terminated, the evaporator fans will: An off-cycle defrost method is often used on evaporators operating at a minimum of; Excessive frost on the evaporator causes:
