Third, the chiller works: by removing the liquid vapor compression or heat absorption refrigeration cycle, vapor compression chillers include four main components of the vapor compression refrigeration cycle test (compressor, evaporator, condenser, forming part of the metering device ). These machines can achieve different refrigerant, the refrigerant and healthy urban water absorption chillers use silica gel as a drying agent, absorption chillers use water as the refrigerant, and between the water and liquefied rely so as to achieve the best cooling effect In most cases, the chilled purified water, ethylene glycol, i.e. other liquids. Fourth, the basic components of the refrigeration system: compressor: Compressor the entire refrigeration system, the core components, the refrigerant is compressed source of power. Its role is to input electrical energy into mechanical energy, the compressed refrigerant. Condenser: condenser in the refrigeration process and play the output energy of the refrigerant to the condensing effect. From the refrigeration compressor discharge superheated high pressure into the condenser, which is in the process of absorbing all of the heat work, including from the evaporator and the refrigerant compressor and the heat absorbed in the pipe are passed to the surrounding medium (water or air) away; high-pressure superheated vapor refrigerant condenses into a liquid. (Depending on the cooling medium and the cooling of the condenser can be divided into three categories: water-cooled condenser, air-cooled condensers, evaporative condensers.) Reservoir: reservoir installed after the condenser, with condensate the drain pipe is directly connected. Refrigerant liquid flows into the condenser should be unimpeded within the reservoir, so that you can take full advantage of the condenser cooling area. On the other hand, when the thermal load changes evaporator, liquid refrigerant requirement also changes, that time, the reservoir will play a role in regulating and storage of refrigerants. For small refrigeration unit system, often do not install the reservoir, but the use of a condenser to adjust and store refrigerant. Evaporator: The evaporator is to rely on the evaporator refrigerant liquid (actually boiling) to be absorbed by the cooling medium heat exchanger equipment. It functions in a refrigeration system is to absorb the heat (or cooling output). To ensure the evaporation process can be stable and lasting, must continue to use the gas vaporized refrigerant compressor pumped to maintain a certain pressure evaporation drying filter: in a refrigeration cycle must prevent moisture and dirt (oil, iron, copper shavings) from entering, the main source of water is the newly added trace moisture in the refrigerant and lubricant contained, or due to overhaul the system and bring air into the water. If moisture is not excluded clean, when the refrigerant throttle valve (thermostatic expansion valve or capillary tube) is passed, because the pressure and temperature sometimes drops of water will solidify into ice, so the obstruction, affecting the normal operation of the refrigeration unit. Therefore, in the refrigeration system must be installed filter drier. Thermal expansion valve: thermal expansion valve in the refrigeration system both flow control valve, but also the throttle refrigeration equipment, which is installed between the filter drier and evaporator refrigeration equipment, its bulb is wrapped at the outlet of the evaporator. Its main role is to make the high-pressure refrigerant liquid at room temperature throttling flow through thermostatic expansion valve, into a low-temperature low-pressure refrigerant wet steam (mostly liquid, a small part of the steam) into the evaporator, vaporized in the evaporator heat, cooling to achieve the purpose of cooling. Electrical automatic control system: electrical automatic control system includes a power supply section and the automatic control section. Power partly through contacts on the compressor, fans, pumps and other power supply. Automatic control section includes temperature control combined with each other, the pressure to protect, delay, relay, overload, etc. to achieve automatic start and stop according to temperature, protection.
