Guides To Choose A Expansion Valve
What do we know about valve specifically expansion valve? By the term itself, it seems to be used in industrial and mechanical equipments or devices. Some of your household appliances have this expansion valve. You will see them inside you refrigerators or coolers which forms part in the compressor system of such that provides heat, ventilation or air conditioning to the system. An expansion valve is a piece of device that helps in reducing pressure in the system. One of the most common types of expansion valve is the thermostatic expansion valve or the TMV. This type of expansion valve is usually used in heating, air conditioning and ventilation system. There are also two types of air conditioner expansion valve they are the thermostatic expansion valves and the capillary tubes. For instance, an expansion valve can either be a capillary tube or thermostatic expansion valve.
The thermostatic expansion valve helps control the flow of the refrigerant at the same time functions at a varying temperatures and pressure points. On the other hand, the capillary tube is in the essence not really an expansion valve because it is just a simply tube but work as an expansion valve because it function the same like any other expansion valve. It is responsible in transmitting the pressure level in the system going to the sensing tube attached in the thermostatic expansion valve that basically functions as a throttle.
The air conditioning unit basically can be divided into three main parts: the compressor, the condenser and the evaporator. The expansion valve forms part of the evaporator. The capillary tube advantages ranges from it being cheap with simple design as well as of low and free maintenance which can be very economical for its users. Furthermore, its affordability and simple designs are very much important especially for equipment and devices with relatively small in nature. On the other hand, the thermostatic expansion valve can work on varying load requirement. This expansion valve is usually used by bigger equipments or devices such as those in manufacturing plants or a big location that needs a big amount of cooling process. However, the disadvantage of capillary tubes is that it operates under a very small or tight variation only. This is because the capillary tube is only small and can only cover small equipments only such as the refrigerator or freezers that you have at home. Furthermore, you will need to consider replacing the tune from the compressor’s exit to evaporator’s inlet if such becomes defective. This can be quite time consuming since you will have to sometimes check the equipment whether such capillary tube is in good working condition or not. On the other hand, the thermostatic expansion valve are quite expensive that the capillary tube. Furthermore, it will require tuning during the first assembly which can be costly if you don’t have any people who knows how to do it right.
In selecting the expansion valve to use, make sure that you are getting a top most quality expansion valve. This is because an insufficient and defective valve may cause safety issues for the people or workers in the manufacturing plant or so forth.
