Corresponding air-conditioning part of air-conditioning duct and attemperater are arranged at refrigerator top from top to bottom, and air-conditioning part corresponding housing is provided with into and out of air port and blowing device.
Air-conditioning part corresponding housing is provided with to outdoor pressure air exhausting device.
Among the present invention, hot-water air-conditioning refrigerator (cabinet) comprises air-conditioning system, attemperater and refrigerator (cabinet) three parts.For the ease of installing and reaching heat exchange effect preferably, the heat exchanger that is used for output hot water adopts sleeve type structure, and interior pipe is that condenser pipe, outer tube are water pipe, and integral body places the foaming layer of refrigerator.Because the compressor horsepower that uses in hot-water air-conditioning refrigerator is much larger than the refrigerator of equal specification, the heat that the compressor that is in operation produces is bigger, and must cool off compressor could normal operation, adopts usually air-cooled compressor to be cooled off.The big heat that produces for compressor is in operation utilizes more fully, and the present invention cools off compressor by warm water at compressor peripheral hardware insulation water jacket.If because low excessively to the compressor coolant water temperature, the exhaust pition of compressor and cylinder body excesssive gap influence its operating efficiency, when adopting the warm water cooling, both can continue to improve water temperature, and can also make compressor be in normal operating temperature all the time, thereby improve the service life of compressor.
Hot-water air-conditioning refrigerator (cabinet) is when normally moving, preferential operation refrigerator refrigeration and heat-exchanger circuit, when the refrigeration of refrigerator reaches requirement such as attemperater water level when not reaching requirement, system automatically switches to air-conditioning and heat-exchanger circuit, when cistern water level reaches requirement, the action of water level travel switch, flow control valve cuts out the water route, and system quits work.If refrigerator also needs work when water tank water is full, system automatically switches to external heat-radiation loop, the recirculated water cooling pipe-line system is cooled off compressor and condenser pipe (air-conditioning duct) in starting simultaneously, and water is incubated the water in the water tank by double pipe heat exchanger simultaneously.
When hydraulic pressure is normal, the water cycle process during normal again water is: running water enters the outlet pipe of attemperater → attemperater through valve → refrigerator delivery port (closed check valve on the interior circulating water pipe) from the compressor cooling jacket → attemperater water inlet pipe of refrigerator water inlet → pressure sensor → flow control valve → tube-in-tube heat exchanger outer tube → band heat-insulation layer.
Water inner cyclic process when storage full water and refrigerator need freeze in, the water tank normal when hydraulic pressure is: (water level travel switch action when cistern water level reaches requirement, flow control valve cuts out into water, three position five-way valve automatically switches to external heat-radiation loop, starting compressor) water in the attemperater is by the compressor cooling jacket of the pump sump mouth → interior circulating water pipe → water circulating pump → check valve → band heat-insulation layer of bottom → get back to attemperater through the attemperater water inlet pipe, finishes to the condensation of air-conditioning duct with to the insulation of water.
Not enough or cut off the water and refrigerator need freeze the time when hydraulic pressure, the pressure sensor that is arranged on the water inlet pipe sends signal, and the control flow control valve cuts out the water route, adopts in the water circulation that compressor and air-conditioning duct (only depend on air cooling effect relatively poor) are cooled off simultaneously.Hydraulic pressure is not enough or cut off the water, water inner cyclic process when refrigerator need freeze is: three position five-way valve automatically switches to external heat-radiation loop, start compressor, the compressor cooling jacket of circulating water pipe → water circulating pump → check valve → band heat-insulation layer in water in the attemperater is sucked by water circulating pump → get back to attemperater through the attemperater water inlet pipe is finished to the condensation of air-conditioning duct with to the insulation of water.
The multi-station changing-over valve pipeline annexation of using in hot-water air-conditioning refrigerator is: the axial tracheae 200 of valve body end cap connects compressor inleting pipe, radially tracheae 200-4 connects the refrigerator evaporation tube, radially tracheae 200-3 connects the compressor return air pipe, radially tracheae 200-2 connects the refrigerator condenser pipe, radially tracheae 200-1 water receiving Tube Sheet of Heat Exchanger.Each station state is as follows:
(1) shown in Fig. 7-1 merit position, the compressor air inlet by axial tracheae 200 through the tracheae 200-2 of the through hole of spools → radially connect the tracheae 200-4 of refrigerator condenser pipe → capillary and filter → radially connect refrigerator evaporation tube → spool connectivity slot → radially tracheae 200-3 connects compressor return air pipe → compressor, thereby the merit position one of finishing the refrigerator refrigeration, in air, dispelling the heat.
(2) shown in Fig. 7-2 merit position, spool is rotated counterclockwise 45 ° by merit position one, the compressor air inlet by axial tracheae 200 through the tracheae 200-2 of the tracheae 200-1 water receiving Tube Sheet of Heat Exchanger → capillary of the through hole of spools → radially and filter → radially connect refrigerator condenser pipe (do this moment evaporation tube with) → spool connectivity slot → radially tracheae 200-3 connects compressor return air pipe → compressor, thereby finish air-conditioning effect, to the merit position two of water heat effect to air cooling.
(3) shown in Fig. 7-3 merit position, spool turns clockwise 135 ° by merit position one, the compressor air inlet by axial tracheae 200 through the tracheae 200-4 of the tracheae 200-1 water receiving Tube Sheet of Heat Exchanger → capillary of the through hole of spools → radially and filter → radially connect refrigerator evaporation tube → spool connectivity slot → radially tracheae 200-3 connects compressor return air pipe → compressor, thereby finish to the refrigerator refrigeration, to the merit position three of water heating.
