The condenser is arranged outdoors, and the air conditioner that uses the outdoor air to cool the condenser is called an air-cooled cabinet type chiller. It is divided into two parts, an indoor unit and an outdoor unit, which are connected by refrigerant pipes and wires. For air-cooled chillers that are purely split-type air conditioners, there are compressors, condensers and fans in the outdoor unit. The main operating equipment is outdoors. The indoor unit has only evaporators and low-noise fans. Easy to install and so on. Another type of chiller is a "away-type condenser" structure. In the outdoor unit, there are only condensers and fans. The main purpose is to remove heat from the outdoor unit, and the compressor is still installed in the indoor unit.

The air-cooled cabinet type air cooler is mainly composed of a compressor, a condenser, a drying filter, an expansion valve (or a capillary tube), an evaporator, an air filter, an indoor and outdoor fan, and the like. The liquid refrigerant enters the evaporator after being throttled by the expansion valve, where it evaporates and absorbs the heat of the cooled air, and then is sucked by the compressor through the return pipe, compressed into high temperature and high pressure superheated steam, and then enters the condenser and is taken outdoors. The air is cooled, the latent heat of vaporization is released and condensed into a high-pressure liquid, which is sent to the expansion valve through the drying filter and then to the next cycle. This continuous circulation will cool the room and maintain it at the proper air conditioning temperature.

The object to be cooled in the air cooler is indoor air. It is first sucked by the fan through the filter screen, sent to the evaporator for cooling and dehumidification, and then sent into the room to mix with the indoor air to reduce the indoor temperature. Due to the closed circulation of indoor air, indoor carbon dioxide will continue to increase, making indoors feel uncomfortable. To this end, a fan should be installed to draw in fresh air from the outside to reduce the indoor carbon dioxide content. The most common type of ventilation is about 5% of the air volume of the chiller. Or it is equipped with an exhaust fan, the effect is the same. When the three-phase power supply of the ventilated cooling chiller is connected, the compressor starts to run, and the indoor and outdoor fans also operate at the same time. The compressor and fan work under the protection of the thermal relay. In case of overload, the thermal relay contacts act and automatically cut off the circuit. The pressure relay also protects the compressor from overpressure. The indoor temperature is controlled by the temperature controller WJ-WJ35. When the temperature reaches the set temperature, it can be stopped automatically. When the indoor temperature rises, the thermostat automatically turns on the circuit, the cooling fan resumes operation, and the cooling continues.

Water-cooled air-conditioning is a commonly used cooling fan. It can be used in workshops, factories, and public places. It can be used in workshops, factories, and public places. The biggest selling point of the air cooler is its energy saving and environmental protection features, which can save more power. The principle of the air cooler is: when the fan starts, the negative pressure will be generated in the cavity, and the air outside the machine will be pressed into the machine. Through the wet curtain, the temperature of the dry bulb coming out of the air cooler is lower than the temperature of the outdoor dry bulb. It is about 12 degrees. This principle makes the difference in air temperature greater and the better the cooling effect. The main components of the air cooler are composed of wet curtain, water circulation system, float valve water supply device, casing and motor. The design of the air cooler is reasonable, saves electricity, and adapts to the needs of the social market. The launch will be recognized by the public, and the market demand is still increasing. Air coolers are closely related to people's lives by advertising applications.

Because of the characteristics of energy saving and environmental protection of cooling fans, not only in the market, but also in the market, it is encouraged by the state. The mobile chillers are developed under such a background. It is based on the user experience and comes with the development principle. The large water tank does not need to be connected to the tap water pipe, it has casters for easy movement, and the integrated standard machine can be used without water supply and plug-in after installation and purchase. The optimized airflow guide makes the air volume large but the wind is soft and comfortable, and the same wind power consumption Only half of the traditional chillers are more energy efficient. The mobile chiller is most suitable for the occasions of large workshop post cooling, equipment maintenance work moving cooling, temporary cooling of warehouse storage and transportation, temporary cooling of outdoor work, and other occasions requiring flexible maneuvering and cooling. The mobile chiller combines the coolness of the air conditioner with the power saving of the fan. The user who can grab the air conditioner in the market can squeeze the fan down. It can be said that the market is very optimistic.

At present, the demand for low-temperature refrigeration in all parts of the country continues to increase, which has laid the foundation for the market demand for chillers. Among them, Beijing, Shanghai, Guangdong and Guangxi to Vietnam are mostly dominated by medium and large-scale cold storage in low-temperature refrigeration construction, and small-scale multi-purpose storage cold storage is mainly used in towns and towns in the second-tier cities of central China. With the upgrading of the agricultural industry in the future, the demand for long-distance transportation will become more and more obvious, and the northeast and northwest markets will become more mature. At the same time, for a long time, the government's support for low-temperature refrigeration enterprises, the introduction of various subsidy policies, and agricultural machinery subsidies have also promoted the development of low-temperature refrigeration industries throughout the country. In 2013, it intends to build a refrigeration industrial chain with cluster advantages. The storage cold storage and fresh-keeping cold storage of various specifications in various parts of the country have started construction. Only Henan Province will build more than 34 food cold storage projects. The number of projects in the national market that add up to the low-temperature refrigeration market is staggering. At the same time, according to statistics, the market demand for low-temperature refrigeration and cold chain project construction in the food industry is the fastest growing, with an annual growth rate of more than 8%.

In the market, the sales volume of the air cooler is relatively large. The market price of the air cooler is relatively stable on average, and there is not much improvement. It is understood that the style of the cooling fan ventilation cooling equipment can be said to be quite a lot. But the price of each type of chiller is different, and each material is different. What kind of material determines the price, this is beyond doubt. The surface of the air cooler is mainly composed of a special fiber corrugated honeycomb wet curtain, a high-efficiency energy-saving fan, a water circulation system, a float valve hydration, a casing, and electrical components. When the fan is running, a negative pressure is generated in the cavity to make the air outside the machine. Flowing through the porous wetted wet curtain surface forces the dry bulb temperature of the curtain air to drop to a wet bulb temperature close to the outside air, ie the dry bulb temperature at the exit of the chiller is higher than outside.

Moving the cooling fan's saturation temperature and saturation pressure The liquid contained in the closed container, the molecules flying out of the liquid surface cannot be expanded to other places, and can only accumulate in the space above the liquid for irregular movement. When some of the gas molecules collide with the liquid surface, they return to the liquid, and some new molecules fly from the liquid surface to the gas space. When the two reach equilibrium, the gas specific volume in the gas space no longer changes, the liquid and Its vapor is in a state of dynamic equilibrium, and the number of molecules in the vapor no longer increases. This state is called saturation. The vapor in this state is called saturated vapor, the temperature of saturated vapor is called saturation temperature, the pressure of saturated vapor is called saturation pressure, and the moving chiller is supercooled and superheated. Under saturated pressure conditions, the saturated steam is continuously heated. The temperature is higher than the saturation overflow, which is called superheat. This vapor is called superheated vapor. The saturated liquid is continuously cooled to a saturation temperature under the condition of constant saturation pressure, which is called supercooling.

The mobile industrial chiller compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant through an advanced rotary hermetic compressor, and then sends it to the condenser to dissipate it into a liquid refrigerant of normal temperature and high pressure, generating heat, which is heated by a centrifugal fan. The air is discharged. Yuyao air cooler, Cixi air cooler

The advantage of the mobile industrial chiller is that there is no external machine, no professional installation, the overall design, equipped with universal casters, free to move, no need to wait for the professional installation, you can easily get it yourself. In a large-area environment or a local air-conditioning environment, the mobile industrial cooling fan can adjust the temperature in the local space to quickly reach the cooling target, and it is very energy-saving.
