Air Conditioner-Refrigeration System Choke

An Air Conditioner-Refrigeration System Choke is a component used in refrigeration and air conditioning systems. It is part of the supply class Refrigeration And Air Conditioning Components, which falls under the supply group Refrigeration, Air Conditioning, And Air Circulating Equipment.

The choke, also known as an expansion valve or metering device, is responsible for regulating the flow of refrigerant into the evaporator coil of the system. It controls the amount of refrigerant that enters the evaporator, allowing for efficient cooling and dehumidification.

The choke works by creating a pressure drop in the refrigerant, which causes it to change from a high-pressure liquid to a low-pressure, low-temperature vapor. This process is essential for the refrigeration cycle to work effectively.

There are different types of chokes used in air conditioning and refrigeration systems, including thermostatic expansion valves (TXV), electronic expansion valves (EEV), and capillary tubes. Each type has its own advantages and is selected based on the specific requirements of the system.

Overall, the choke plays a crucial role in maintaining the proper functioning of an air conditioner or refrigeration system by controlling the flow of refrigerant and ensuring efficient cooling and dehumidification.
