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 valuable is the thermal expansion valve.Many TXVs are designed for a wide range of air conditioning, refrigeration, heat pump, and chiller applications.
Many use stainless steel power elements that are unsusceptible to corrosion. They proposal products with conventional, as well as stable ported designs that are useful when applied to systems with large load variations and/or floating head applications. Organization also manufactures bi-flow designs for use in heat pumps and many of our TXVs have a take-apart design for ease of service. Company thermal expansion valves cover a wide range of nominal capacity, from ½ ton to 100 ton.
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 desired, 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 knows when it’s time to check or change the air filter in your cooling system.
A thermal expansion valve is animportant element to a heat pump; the cycle that makes air conditioning, or air cooling, promising. A simple refrigeration cycle consists of four main elements, a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air conditioning occurs. The cycle starts when refrigerant enters the compressor in a low-pressure, moderate-temperature, gaseous form. The high-pressure and high-temperature gas then enters the condenser. The condenser converts the high-pressure and high-temperature gas to a high-pressure liquid by transferring heat to a lower temperature medium, usually ambient air.
