Capillary tube control the flow of refrigerant by maintaining their enthalpy same.

QUESTION: 8

Capillary tube is not used in large capacity refrigeration system because

Solution:

The capillary tube is not used in large capacity refrigeration systems because Capacity control is not possible.

QUESTION: 9

Which one of the following is the most important function of thermostatic expansion valve

Solution:

Thermostatic expansion valve maintains constant degree of superheat in the evaporator.

QUESTION: 10

In on-off control refrigeration system, which one of the following expansion devices is used?

Solution:

On-off control is done by thermostat. In the On- off control of the air-handling unit, the fan motor is operated intermittently by the room thermostat the bulb of which is installed in the return air.
