Detailed description of the invention

With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.

The structure of a kind of air-conditioning system of this utility model is as it is shown in figure 1, include chilled water system With coolant VMC (Ventilation Mechanical Control System):

Chilled water system includes water pump 1, and the water inlet of water pump 1 is intake with tap water by three-way valve The outlet pipe of pipe 2 and radiant panel 3 connects;The outlet of water pump 1 enters with the cold water of heat exchanger 4 Mouth connects, and the cooling water outlet of heat exchanger 4 is connected with the water inlet pipe of radiant panel 3;Coolant new wind system System includes new blower fan 5, new blower fan 5 refrigerant exit, heat exchanger 4 refrigerant exit, new blower fan 5 Refrigerant inlet and heat exchanger 4 refrigerant inlet are passed through with the four-way change-over valve 8 in off-premises station 7 respectively Refrigerant pipe connects, and is provided with air supply duct 15 at the air outlet of new blower fan 5, air supply duct 15 End is provided with new wind air outlet 16.Wherein, tap water water inlet pipe 2 is provided with water softener 13. Water pump 1, water softener 13 and heat exchanger 4 are integrally disposed in silencer box 14.Radiant panel 3 is Metal radiant panel.New blower fan 5 includes that housing, housing are respectively arranged at two ends with new wind air inlet and go out Air port, in housing, new wind air inlet is disposed with filter, evaporation coil between air outlet And pressure fan, it is additionally provided with return air air inlet between new wind air inlet and filter.Off-premises station 7 wraps Including housing, housing is provided with blower fan 9, is provided with compressor 10 in housing, and compressor 10 is with cold Solidifying coil pipe 11, electric expansion valve 12 and four-way change-over valve 8 pass sequentially through refrigerant pipe and connect.Even The refrigerant pipe connecing four-way change-over valve 8 and new blower fan 5 refrigerant inlet is provided with electromagnetic valve 6.Radiation Plate 3 is arranged according to division unit, the corresponding new wind air outlet of each radiant panel 3 unit 16, carry out humid control;Silencer box 14 is made an uproar for equipment such as water pump, heat exchanger, water softener The appropriate elimination of sound, optionally determines that silencer box is placed on indoor or outdoor, and silencer box should be tied Close actual field to decide whether to use.

A kind of air-conditioning system of this utility model operation principle and process in summer is: this is Unite and include three work process:

The work process of chilled water system: recirculated water enters in heat exchanger via water circulating pump, circulation Heat in water is taken away by coolant, and circulating water temperature reduces, and the recirculated water of low temperature is from heat exchanger Out, enter metal radiant panel through feed pipe to pass through metal radiant panel and indoor occupant, go along with sb. to guard him knot Structure inner surface, equipment surface carry out radiation heat transfer, and water temperature raises, and the recirculated water of high temperature is through backwater Pipe and water circulating pump enter at this in heat exchanger and carry out heat exchange with coolant, so complete water system Cyclic process.When water system needs moisturizing, can be by water softener by real after water treatment Existing system water supplement.

The work process of coolant system: it is high that coolant becomes high temperature through compressor compression in off-premises station The gas of pressure, condensation heat release liquefaction, then the electric expansion valve in off-premises station within the condenser Further decrease temperature and pressure, the liquid of low-temp low-pressure is out partly into heat exchange from off-premises station In device, in evaporation endothermic, with heat exchanger, the water of secondary side carries out heat exchange, and another part enters new Evaporation endothermic in the evaporation coil of blower fan, outside cooling chamber, new wind, goes out from heat exchanger and new blower fan The gas of the high-temperature low-pressure come returns compressor pressurization and heats up, and so completes refrigerant circulation mistake Journey.

The work process of wind system: when system just starts, due to outdoor air relative humidity relatively Greatly, temperature is higher, so at this time valve closing on the new wind blast pipe on new blower fan, return air Mouthful open, utilize and compare the most relatively low indoor return air of outside air humidity, temperature at new blower fan Humidity load in first decontamination chamber after reason, during to guarantee that whole air conditioning system is opened, energy consumption is relatively low, when During system run all right, return air inlet is closed, and the valve opening on new wind blast pipe, system starts Supplementing new wind, outdoor new wind or indoor return air enter new from new wind air inlet or return air air inlet Blower fan, with evaporation coil heat exchange after being filtered, after through blower fan from air outlet through blowing Each room sent into by pipeline.

Coolant process in the winter time is the most contrary with summer, and this process can be by four in off-premises station Logical reversal valve realizes.

This utility model is suitable for whole year operation, has following several operation mould according to the demand of client Formula:

1. air-conditioning system

In weather environment Arid Area, the dew point temperature of room air is less than metallic plate radiating surface Temperature time, new blower fan can be closed, it is achieved pure radiant panel for cooling and heating.

2. domestic radiation central air-conditioning system

New blower fan and radiant panel work simultaneously, and independent temperature-humidity control uses humidity stress field Principle, utilize the relative humidity of Xingfeng capsule room air, according to the temperature of indoor air And relative humidity, regulation determines the plate surface temperature of radiant panel.
