1.	Write the names of different refrigerant control devices. Give advantages and disadvantages of capillary as an expansion device as compared to an expansion valve.
Answer» The different refrigerant control devices are:- (1.) Capillary tube (2.) Thermostatic Expansion valve (3.) Automatic expansion valve (4.) High side float valve (5.) Low side float valve (6.) Solenoid valve Advantages of capillary tube as compared to expansion valve:- (1.) It is simple in construction. (2.) No maintenance is required. (3.) Cheap and economical. (4.) System does not require receiver. Disadvantages of capillary tube as compared to expansion valve:- (1.) The refrigerant must be free from moisture and dirt otherwise it will choke the tube and stop the flow of refrigerant. (2.) Only can be used with small capacity units. (3.) It cannot be used with high fluctuating load conditions.
