Finpower Aircon Interview Questions and Answers

Refrigeration cycle is a process of removing heat from a low-temperature reservoir and transferring it to a high-temperature reservoir.

• The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.

• The refrigerant is compressed by the compressor and then condensed in the condenser, releasing heat to the surroundings.

• The high-pressure liquid refrigerant then passes through the expansi...read more

Thumb rule to calculate TR

• TR (Tonnage Refrigeration) = 12,000 BTU/hr

• For example, a 3 TR air conditioner can remove 36,000 BTU of heat per hour

• TR is used to measure the cooling capacity of air conditioning systems

VRF and VRV are both air conditioning systems that use refrigerant to cool or heat a space, but VRF is a more advanced version of VRV.

• VRV stands for Variable Refrigerant Volume and is a trademark of Daikin Industries, while VRF stands for Variable Refrigerant Flow and is a generic term used by other manufacturers.

• VRV systems have a limited number of indoor units that can be connected to a single outdoor unit, while VRF...read more
