Types of Expansion ValvesIn a cooling system, especially in air conditioning, the Expansion Valve has several types that you can choose according to your individual needs. Here are the types:1. Capillary Pipe Type Expansion ValveExpansion Valve is a valve that has a heat sensing tube that functions to measure the temperature or the temperature of the freon coming out of the evaporator. The heat received by the heat sensing will be used to regulate the freon supplied by the expansion valve to the evaporator.2. Orrifice Type Expansion ValveIn contrast to the type of capillary tube, the Expansion Valve uses an orifice to regulate the freon that is channeled to the evaporator.3. Box Type expansion valveExpansion Valve is the type most commonly used today. This Expansion Valve uses temperature and pressure sensors to regulate the amount of freon that flows from the valve to the evaporator.Expansion Valve Function1. Lowering the pressure of freon or refrigerantThe main function of the Expansion Valve is to lower the freon or refrigerant. The reason is, the high freon pressure resulting from compressor compression needs to be lowered in order to work effectively.2. Cooling the temperature of the freon or refrigerantThe second function of the Expansion Valve is to cool the temperature of the freon or refrigerant to 30 degrees Celsius.3. Regulating the amount of Freon or Refrigerant supplied to the evaporatorThe last Expansion Valve function is to regulate the amount of freon or refrigerant that is channeled to the evaporator according to the AC cooling load. The hotter, the more freon is channeled, and vice versa.
That's the Expansion Valve discussion that you need to know, besides the Expansion Valve, you also need AC pipes, AC filters, overloads, AC manifolds, temperature controls, and other AC spare parts. If you need expansion valves or other products, you can find a wide selection of products from quality suppliers in Indotrading.
