The cold water machine known as the refrigerator, freezer, ice water machine, cold water machine, cooling machine, water cooling machine, because of the widely used in all walks of life, so the name is much too many to count. The nature of the principle is a versatile machine that removes the liquid vapor through the compression or thermal absorption refrigeration cycle. Vapor compression chiller consists of four main components of the vapor compression refrigeration cycle compressor, evaporator, condenser, part of the metering device to achieve a different form of refrigerant. Using water as refrigerant absorption chiller, and rely on between water and lithium bromide solution to achieve the cooling effect, strong affinity.
Refrigeration is an industrial refrigeration equipment for recycling liquid cooling to achieve the required temperature and improve the production efficiency (also called: cold water machine, ice machine, refrigerator, freezer, cooling machine, water cooling machine). The liquid can flow through the heat exchanger to the purpose of cooling the air or equipment. The water vapor compression unit consists of four major components of the vapor compression refrigeration cycle (compressor, evaporator, condenser, a dry filter, thermal expansion valve), these components play a most important link in the refrigeration refrigeration process.
The plurality of compressors in parallel, each compressor with an independent cooling loop, namely the evaporator and condenser are completely independent; all the compressor by the unified command control system, open and shut down one by one, each other will not interfere with each other, plus chuanben brand machine all adopt imported genuine single production, low failure rate based on the above reasons, this series can ensure that the machine has a highly stable performance, long continuous operation in case of choice
Basic components of a refrigeration system
Compressor: the compressor is the core component of the whole refrigeration system, and also the source of the power of the refrigerant compressor. It is the role of the input of the electrical energy into mechanical energy, the refrigerant compression.
Evaporator: an evaporator is a heat exchanger which is absorbed by the heat of the cooling medium, depending on the evaporation of the refrigerant liquid (actually boiling). The function of it in the refrigeration system is to absorb the quantity of heat (or cold). In order to ensure that the evaporation process can be stable and lasting, it is necessary to constantly use the refrigeration compressor will be the evaporation of gas pumping away, in order to maintain a certain evaporation pressure.
Condenser: in the process of refrigeration, the condenser has the function of outputting heat energy and condensing the refrigerant. High pressure steam discharged from the compressor enters the condenser, the heat will be absorbed in the work process, including from the evaporator and the compressor and the heat absorption in the pipeline are transferred to the surrounding medium (water or air) away; high pressure refrigerant steam condenses into liquid again. According to the different cooling medium and cooling way, the condenser can be divided into three types: water cooled condenser, air-cooled condenser and evaporative condenser.
Thermal expansion valve: thermal expansion valve in the refrigeration system is a flow control valve, throttle valve and refrigeration equipment, which is installed between the drying filter and evaporator in refrigeration equipment, temperature sensing bag is wrapped in it at the outlet of the evaporator. Its main role is to make the refrigerant liquid with high pressure and normal temperature in the flow through the thermostatic expansion valve throttle step-down, into a low-temperature low-pressure refrigerant vapor (mostly liquid, small part of steam) into the evaporator, vaporization in the evaporator endothermic, and achieve the purpose of refrigeration.
Dry filter: to prevent water and dirt in the refrigeration cycle (oil, iron, copper) into the water, is the main source of trace water to add new refrigerant and lubricating oil containing, or due to the maintenance system of air into the water. If the system does not exclude the water clean, when the refrigerant through the throttle valve (thermal expansion valve or capillary), due to decreased pressure and temperature sometimes water will solidify into ice, the channel blocking, affect the normal operation of refrigeration equipment. Therefore, the drying filter must be installed in the refrigeration system.
After the condenser is installed in the condenser, the liquid discharging pipe of the condenser is directly connected with the liquid storage device. Liquid refrigerant condenser should be smoothly flowing into the reservoir, which can make full use of the cooling area of the condenser. On the other hand, when the heat load of the evaporator is changed, the requirement of the refrigerant liquid is changed, then the liquid storage device plays the role of regulating and storing the refrigerant. For small refrigeration systems, the use of a condenser to regulate and store the refrigerant is often not installed.
Refrigerant: most industrial refrigerators used in the modern industry are using R22 or R12 as refrigerant. Refrigerant is the working fluid in the refrigeration system, its main function is to carry heat, and to achieve heat absorption and heat release when the state changes.
The working principle of chuanben brand refrigeration machine
According to the principle of refrigeration system, the liquid refrigerant of low temperature and low pressure and the surrounding medium in the evaporator heat exchange inside the evaporator to absorb heat and evaporate into the low temperature and low pressure gaseous refrigerant, constant temperature evaporation process, volume change, low temperature and low pressure gaseous refrigerant enters the compressor, the compressor, compressed into high temperature and high pressureThe gas enters the condenser, the condenser and the indoor in medium heat exchange, the heat part of high temperature and high pressure gaseous medium is absorbed, medium temperature, medium high temperature cooling water / cooling fan exhaust condenser, refrigerant condenser heat into high temperature and high pressure liquid outflow, after drying the drying filter after filtration, the inflow of expansion valve throttle, throttle step-down, rapid cooling process, low temperature and low pressure liquid refrigerant into the refrigerant into the evaporator, and the heat of evaporation, so as to realize the whole process of refrigeration system;
One of the cold water machine model, the room temperature of the water through the cold water machine compressor cooling to a certain temperature to strengthen the cooling of the mould or machine, as single use, the heat dissipating device is a built-in fan, there are three interrelated systems: the refrigerant circulation system, water circulation system and electric control system. 　　
Refrigerant circulation system:
The liquid refrigerant in the evaporator to absorb the heat from the water and began to evaporate, a certain temperature difference between refrigerant and the final water, the liquid refrigerant is completely evaporated into gas, after the compressor suction and compression (pressure and temperature increase), gaseous refrigerant absorbs heat through the condenser condenses into liquid. Through the expansion valve (or capillary) after the throttle into a low-temperature low-pressure refrigerant into the evaporator, complete the refrigerant cycle process. 　　
Water circulation system:
Pump is responsible for pumping water from the tank to the user to cool the equipment, frozen water will heat away after the temperature rise, and then return to the freezer. 　　
Electrical control system:
Including the power part and the automatic control part. 　
The power supply part is through the contactor, to the compressor, the fan, the water pump and so on. 　　
The automatic control part comprises a temperature controller, pressure protection, overload protection, delay relay, etc. are combined to achieve the automatic start and stop according to the temperature, protection and other functions.
