Figure 1.3 shows the basic components of a vapour compression refrigeration system. As shown in the figure the basic system consists of an evaporator, compressor, condenser and an expansion valve. The refrigeration effect is obtained in the cold region as heat is extracted by the vaporization of refrigerant in the evaporator.
Main parts of a refrigeration The main parts of a refrigeration system are shown diagrammatically in the figure below. The six primary components of the system include the thermostatic expansion valve, evaporator, capacity control system, compressor, condenser, and receiver. All refrigeration systems must also be fitted with a relief valve.
1999-9-23 · Evaporator: This is the part of the refrigeration system that is doing the actual cooling. Because its function is to absorb heat into the refrigeration system (from where you don't want it), the evaporator is placed in the area to be cooled.The refrigerant is let into and measured by a flow control device, and eventually released to the compressor.
2019-9-20 · electronic expansion valves will be installed on the coil inlet, coil outlet, and in the discharge air. (Some supermarkets require a 4th sensor in the return air). Case controllers will be located in the electrical raceway or under the case. Thermostatic Expansion Valve Location An Alco balanced port expansion valve model is furnished
units, while the expansion valves are used in the large refrigeration units as shown in figure (9). The capillary tubes are copper tubes w ith diameter d = 2 ~ 5 mm and length L

2018-12-10 · Figure 1. The refrigeration system. In a typical refrig-eration system, the compressor sends hot gas to the condenser. Then the condensed liquid passes through an expansion valve into the evaporator where it evap-orates and collects heat from the area to be cooled. The gaseous refrigerant then enters the compressor
2020-7-30 · Some of the prominent parts of the thermostatic expansion valve or TEV are: the metallic body, metallic diaphragm, power element comprising of the feeler bulb and tubing, valve seat and needle that form the orifice, spring, inlet and outlet port connected to the condenser and the evaporator, etc. This the upper portion of the thermostatic expansion valve inside which the gas is filled.
2020-7-31 · Thermostatic expansion valve or TEV is one of the most commonly used throttling valve for the refrigerator and air conditioning systems. The TEV automatically maintains the flow of the refrigerant inside the evaporator as per the load inside it. TEV enables safe running of the compressor without flooding and also helps the refrigeration plant run as per the optimum capacity.
2019-1-22 · Many modern refrigeration systems have an emergency expansion valve which can be set manually in a similar way. Manually operated expansion valves have the disadvantage of being unresponsive to changes in load or sea-water temperature and must be adjusted frequently. The valve itself is a screw down needle valve dimensioned to give fine adjustment.
The purpose of the thermostatic valve is to control the rate at which the refrigerant passes from the liquid line into the evaporator and to keep the pressure difference between the high and low pressure sides of the refrigeration system. The thermostatic expansion valve consists of a diaphragm operated valve (see Fig. 13.9(a and b)). One side .
The thermostats constantly read the temperature of their specific zone, then open or close the dampers within the ductwork according to the thermostat's settings. Not only is system zoning helpful for houses with inconsistent room temperatures, but it's also great for heating or cooling individual bedrooms based on the desired temperature setting.
