what is chiller

The chiller, refrigerator, ice water machine, freezing water machine, cooling machine, etc., because the use of various industries is more extensive, so the name is too numerous. The principle is a multifunctional machine that removes liquid vapor through a compression or heat absorption refrigeration cycle. Vapour compression chiller consists of four main components of vapor compression refrigeration cycle of the compressor, evaporator, condenser, the form of a part of the metering device so as to realize the different refrigerants. The absorption chiller USES water as the refrigerant, and depends on the water and the lithium bromide solution, the cooling effect is very strong.

Chiller is generally used in air conditioning unit and industrial cooling. In air conditioning system, chilled water is usually assigned to the heat exchanger coil in the air handling unit or other types of terminal equipment cooling in its own space, then the cooling water distribution back in cooling by cooling. In industrial applications, cooling pumps for chilled water or other liquids are made through processes or laboratory equipment. The industrial chiller is used to control the products, mechanisms and industries of machinery cooling.

The chiller can be divided into water cooling and air cooling in the form of refrigeration. In technology, water cooling is more than 300 to 500 kcal/h higher than air cooling energy efficiency. In price, water is much colder than air. On the installation, water should be included in the cooling tower for use, air cooling is removable, without other auxiliary, but air-cooled chiller with fan cooling, only to environmental requirements: such as ventilation, humidity, temperature is not above 40 ° C, air ph...

The performance form of the chiller can be roughly divided into:

Cold water machine performance 1: air-cooled chiller - features.

1. No-load cooling tower, easy to install, easy to move, suitable for water shortage of water tower.

2. Low noise fan motor, excellent cooling and condensation effect, stable throttling mechanism, excellent anti-rust treatment.

3. Imported high performance compressor, high EER value, low noise and stable operation.

Cold water machine performance 2: water-cooled chiller - features.

1. Ergonomic panel, full automatic control, equipped with precision electric temperature controller, can run smoothly for a long time.

2. High efficiency heat exchanger, less loss of cold quantity, easy to return oil, heat pipe will not have the advantage of freezing crack.

3. Imported high performance compressor, high EER value, low noise and stable operation.

Cold water machine performance 3: air-cooled cold water chiller - features.

Low temperature cold water machine is special designed for the special low temperature environment cold water machine, its strong refrigeration capacity for hotels, restaurants, supermarkets and other places of business of food preservation, large cold storage meat, seafood, frozen, cold storage, ice-making fields, frozen food processing/cold storage, pharmaceutical, chemical and other various cryogenic environment provides a reliable guarantee.

1. The product variety is complete, including high temperature, water temperature 5 ℃), medium temperature (the temperature - 10 ℃), low temperature (water temperature 15 ℃) three series.

2. The structure is highly optimized, and the heat exchanger plate is used to support the body. The structure is simple and compact and practical.

3. The perfect combination of high quality screw compressor + the best high efficiency heat exchanger can be as high as 4.5.

Characteristics of water-cooled cryogenic chiller.

Water cooled chiller is small in size, large capacity, using imported world famous brand compressor, low temperature performance is outstanding, reliable and durable, the product design based on the characteristics of industrial application, a built-in low temperature water circulating pump and the stainless steel water tank, frozen convenient in use, all materials in contact with the water with corrosion resistant materials, effectively prevent rust, corrosion, microcomputer, the number of leds, the controller with temperature display, set temperature, automatically adjust the cold water temperature and the compressor delay protection function, choose brand contactor, relay and other electrical components, equipped with perfect lamp, switch, operating at a glance, the built-in electronic water level indicator and alarm device, low water level automatic alarm, the operator through the control panel can control cold water tank water level, timely and hydrating, unique modular design, each compressor system security independent, even if a system appear problem, also will not affect the normal work of the other systems.

Cold water machine performance 5: air - cooled screw chiller - characteristics.

Air-cooled condenser for finned, hydrophilic aluminum foil, with double oil ripple by professional processing equipment manufacture of heat exchanger, with compact structure, small volume, light weight, in the advantages of high thermal efficiency, and configure the low speed axial flow fan, can effectively reduce the running noise, reduce the effect on the surrounding environment.

2. The unit control system adopts imported PLC program controller, and the machine interface is equipped with a large screen touch screen. The interface is simple and easy to operate and easy to operate.

Cold water machine performance 6: air-cooled heat pump unit - characteristics.

1. High efficiency and energy saving, comprehensive energy efficiency ratio up to 8.0, can provide refrigeration, heating, the production of domestic hot water three working conditions, according to the environment temperature and hot water demand all automatic switching, make full use of energy.

2. Investment profit, the cold quantity recovery when making hot water can realize the zero cost of refrigeration.

3. The security environmental protection to refrigerant as a medium, non-toxic, no explosion danger, can be connected to the original hot water system, can replace high risk more, the high cost of boiler furnace system, can also be used with solar energy systems, instead of the electric heating part.

4. Fully automatic computer control, which can be operated by remote or centralized management system without special person monitoring.

5. Unit type or modular type, assembling structure, small size, flexible installation in the roof, patio or machine room, etc.

6. The cooling air discharged in hot water can be used to reduce environmental temperature and improve environmental quality.

Characteristics of water-cooled screw unit.
