Air Conditioning Thermal Expansion Valve A Feature to Seriously Consider

Air Conditioning Thermal Expansion Valve

High-efficiency air conditioning systems contain numerous sophisticated components that improve the equipment’s overall performance and energy efficiency. One of the most useful is the air conditioning thermal expansion valve. This device, also known as a thermostatic expansion valve, a TXE, or a TEV, will improve your air conditioner’s efficiency and reduce the amount of money you spend each month on your cooling costs.

In the basic operation of an air conditioner, refrigerant flows through a series of indoor and outdoor pipes, or coils. As it flows through the system to the indoor evaporator coil, the refrigerant changes a liquid to a gas. During this change, the refrigerant absorbs heat, which is then carried away from the inside of your home. When the refrigerant is compressed in the outdoor coils, it changes back to a liquid and releases the heat it contains.

A thermal expansion valve assists in this process by controlling the amount of refrigerant that flows through the system. The valve changes size automatically in response to changing cooling demands placed on your air conditioner. When more cooling is needed, the valve opens wider to allow more refrigerant to flow through the evaporator and condenser coils. As cooling needs decrease, the thermal expansion valve reduces refrigerant flow. This type of flow control dramatically improves system efficiency.

Some other features to look for when choosing a high-efficiency air conditioner include:

  • Variable-speed air handler: Changes speed in response to the amount of air circulation needed to move cool air from the HVAC unit to your home.
  • Fan-only switch: A switch that allows you to turn off the compressor and use the air conditioner for fan-based ventilation only.
  • Filter change indicator: A light or other indicator that lets you know when it’s time to check or change the air filter in your cooling system.
