1. comfort air conditioning:

The air conditioned rooms meet the requirements of human life, to human comfort requirements to control room air parameters.

2. technology of air conditioning:

Also known as the constant temperature and humidity air conditioning, indoor air temperature, humidity, airflow speed, cleanliness, and other parameters to control within a certain range to meet the requirements of the production process.

Cooling capacity: 3,

Air conditioners for refrigeration at run time, the unit of time low-voltage side of the refrigerant in the evaporator absorption of heat, the common unit for W or KW.

4. heat pump heating:

Air conditioner with heat pump heating runtime (heat pump for auxiliary electric heater should run at the same time) unit of time into a confined space, the room or area.

5. performance coefficient:

Cooling (heat) cycle of cooling (heat) and cooling (heat) is the ratio of the power consumption for the coefficient of performance. Refrigeration EER, when called with EER represents: systemheat called performance coefficient expressed by COP.

6. refrigerants:

Refrigerants, refrigeration, is the refrigeration system complete refrigeration cycle of work in the media. Refrigerants in the evaporator draw object by cooling and heat of evaporation, condenser heat to the surrounding air or water is condensed into the liquid. Refrigerator with refrigerants, refrigeration state changes.

7, refrigerant:

Refrigerant is an indirect refrigeration system used to transmit the chilling of intermediate media. Refrigerant in the evaporator is cooling the refrigerant to cooling equipment cooling, absorption cooling object or environment of heat, and then returns the evaporator is refrigerant renewed cooling loop, so as to achieve the aim of continuous refrigeration.

8, fan-coil:

Set the central air-conditioner system commonly used heat exchanger, finnedtubes and air blower, etc, the refrigerant flowing through the air blower plate Tube (tube) and Park air heat exchangers, cooling the air. Fan-coil air cooling device.

9, water cooled chiller:

Water cooled chiller belongs to the central air conditioning system part of the refrigeration unit, its refrigerant to water, as water chillers and cooling condenser for the use of normal temperature water heat exchanger cooling, so called cold water unit. And water cooler relative called air cooling units, air cooled condenser by room air of forced ventilation heat exchanger cooling purposes.

10, cooling tower:

The water through the air is cooling equipment, installed in the top of the building. In refrigeration, electric power, chemical industry and so many industries, from the condenser and other equipment in the exhaust heat of cooling water is recycled after cooling towers.

11, VRV system:

Is short for VariableRefrigerantVolume system, that is, a variable-refrigerant-flow system. In the form of a set of functional outdoor machine, machine and constant speed machine, variable frequency machine. Through parallel outdoor machine system, cooling tube-set into a piping system, can easily under indoor capacity of match, suitable for indoor capacity from 122.5 to choose 1.5KW of differential, that is, up to a group of outdoor unit can be connected with 30 indoor unit. Indoor unit with the ceiling embedded, wall, floor-standing. Type different indoor unit can be connected to a refrigeration circuit and can be individually controlled. Indoor single minimum capacity for 0.6KW maximum 3.75KW, indoor capacity available in the outdoor unit capacity of 50% to 130% adjustment.

12. module machine:

In VRV system developed on the basis of, in 1985 year from Australia jiefeng group invented and designed applications. It combines traditional freon lines changed to water systems, indoor and outdoor machine into a refrigeration unit, indoor fan coil instead. Use of refrigerant water heat exchangers for the refrigeration process, module machine because according to cooling load requirements for automatic adjustment of the starting unit number, enable flexible combination.

13. piston chiller:

Reciprocating chillers is to achieve refrigeration cycle required piston compressor, auxiliary equipment and accessories for compact and assembled together exclusively for the purpose of the use of air conditioning cold refrigeration unit of the integral. Reciprocating chillers stand-alone refrigeration from 60 to 900KW, applies to, not engineering.

14. screw chillers:

Screw chiller is available frozen water in large refrigeration equipment. Commonly used in national defense research, energy development, transportation, hotels, restaurants, light industry, textile, air conditioning, as well as hydraulic and electric engineering of frozen water. Screw chillers is screw compressor, condenser, evaporator, and automatic control without parts and instruments, such as the composition of a complete refrigeration systems. It has compact structure, small volume, light weight, small size, easy to maintain the advantages, smooth, and access to a wide range of applications. Its stand-alone refrigeration capacity from 150 to 2200KW, suitable for medium and large projects.

15 £ ® centrifugal chiller:

By centrifugal compressor and evaporator, condenser and throttle control devices as well as the entire electric table composed of chillers. Stand-alone refrigeration capacity from 700 to 4200KW. It applies to a large and very large projects.

16. LIBR absorption chiller:

To thermal energy as a driving force, taking water as refrigerant to lithium bromide solution as the absorbent, producing more than 0 ° c chilled water, can be used as air conditioning or production process of cold source. Lithium bromide absorption to heat energy to moveForce, common has fired, steam, hot water, the three types of cooling capacity range from 230 to 5800KW, suitable for medium, large, extra large projects.
