Expansion valve
Expansion valve An Expansion valve is a crucial component in refrigeration and air conditioning systems, responsible for: 1. Reducing pressure: Reducing the high pressure of the refrigerant fluid from the condenser to the evaporator. 2. Metering flow: Regulating the flow of refrigerant into the evaporator. Types of expansion valves: 1.Thermostatic Expansion Valve (TXV): - Uses a temperature-sensing bulb to regulate flow. - Most common type used in air conditioning systems. 2. Capillary Tube Expansion Valve: - Uses a small diameter tube to restrict flow. - Often used in small refrigeration systems. 3. Electronic Expansion Valve (EXV): - Uses electronic controls to regulate flow. - Often used in high-performance systems. Key characteristics: 1. Orifice size: Controls the amount of refrigerant flow. 2. Spring tension: Adjusts the valve's opening pressure. 3. ...
