Mitsubishi Ductless Split in Newport News – An Expansion Valve.
An expansion valve is a piece of equipment that reduces pressure in a system. The most common form of expansion valves is a thermal expansion valve (TMV), which is used in heating, ventilation, and air conditioning (HVAC) systems. The two main types of air conditioner expansion valves are thermostatic expansion valves and capillary tubes.
Ductless Split Air Conditioner in Newport News – The Entire Process.
The entire process is performed under pressure, which requires the use of a thermostatic expansion valve. When the pressure inside the compressor reaches a preset level, the thermostatic expansion valve opens, which allows the pressure to decrease. The Freon® then moves through the valve to the evaporator. This maintains both the flow and pressure within the air conditioning system.
The capillary tube contains a filter on one end made of a fine mesh, which prevents debris from getting inside the tube. It works in much the same way as a thermostatic expansion valve, but it cannot withstand significant changes in temperature or pressure. The capillary tube is designed for constant temperature and pressure, and operates as a throttle between the condenser and evaporator.
The tube is typically long and narrow to allow for some Freon® evaporation to occur as it travels through the tube. This is required in order to make the Freon® entering the evaporator similar in temperature to that already in the evaporator. Similar temperatures make the system run more efficiently and speed up the cooling process.
