Description
Technical field
The utility model relates to a kind of family expenses, commercial central air-conditioning.
Background technology
In some areas, because winter, outdoor chilling temperatures was low, the air heat pump unit is difficult to normal operation.Though the technology of frequency conversion at present can solve some problem to a certain extent, when the temperature below-5 ℃, effect is still very poor, and the Energy Efficiency Ratio of air heat pump unit sharply descends, and energy consumption is serious.For solving refrigeration in summer, Winter heat supply, prior art is to use air-conditioning summer, and overlap indoor heating systems with two of heating installation winter.Problems such as particularly heating system exists heat radiation slow, wastes energy, and takies effective usable floor area in the house, and is not attractive in appearance.
Summary of the invention
The purpose of this utility model provides a kind of central air conditioner system, can solve the technical problem that freeze summer and Winter heat supply two cover systems unite two into one.
The structure of central air conditioner system described in the utility model comprises: outdoor section, several indoor four control heat exchangers and supplying heat sources of being made up of several outdoor heat exchangers and blower fan, several compressors and four-way change-over valve; The first cold-producing medium port of described each outdoor heat exchanger is connected with first port of corresponding four-way change-over valve, and the throttle mechanism of the second cold-producing medium port of each outdoor heat exchanger by correspondence is connected with a refrigeration port of corresponding indoor four control heat exchangers; Second port of described four-way change-over valve is connected with another refrigeration port of corresponding indoor four control heat exchangers, and third and fourth port of four-way change-over valve is connected with the turnover port of corresponding compressor respectively; Two heat supply ports of described each indoor four control heat exchangers are connected with two ports of a supplying heat source respectively.
Aforesaid central air conditioner system, supplying heat source wherein are traditional hot water heaters, and the connecting line of itself and indoor four control heat exchangers is provided with water pump.
Aforesaid central air conditioner system, four control heat exchangers wherein comprise blower fan, cold-producing medium coil pipe and hot-water coil pipe.
Advantage of the present utility model and good effect are as follows:
1, only needs a cover system just can solve all changes in temperature problems, reduce investment outlay.
2, all furred ceiling is installed and is not taken effective usable floor area and attractive in appearance in the room.
3, one or four control heat exchangers are established in each room, and refrigeration, indoor each regional temperature of heat supply all can be controlled separately.
4, when winter indoor nobody the time air-conditioning can be closed or transferred to minimum antifreeze temperature, when reusing because the characteristics that native system has rapid heat dissipation greenhouse rapidly, save the energy, save the user heating expense, help the implementation of national heating cost household metering policy.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
The specific embodiment
Referring to Fig. 1, summer is when freezing, the gas that HTHP is discharged in compressor 1 work through four-way change-over valve 2 to outdoor heat exchanger 3, becoming low pressure liquid at the liquid that is condensed into HTHP after the heat release under the effect of blower fan behind throttle mechanism 4 evaporates to indoor four control heat exchangers, 5 cold-producing medium coil pipes, heat becomes gas in the absorption chamber under the effect of four control heat exchangers, 5 blower fans, get back to compressor through four-way change-over valve 2, shown in the accompanying drawing solid arrow.
Excessively season is during heat pump heat supply, the gas that HTHP is discharged in compressor 1 work through four-way change-over valve 2 to indoor four control heat exchangers, 5 cold-producing medium coil pipes, the liquid that is condensed into HTHP after heat release under the effect of four control heat exchangers, 5 blower fans becomes low pressure liquid to outdoor heat exchanger 3 evaporations behind throttle mechanism 4, behind the heat of 3 li absorptions of outdoor heat exchanger low-temperature heat source, become gas, get back to compressor through four-way change-over valve 2, shown in the accompanying drawing dotted arrow.
Cold season in winter, during the air heat pump cisco unity malfunction, compressor 1, outdoor heat exchanger 3 quit work.Other thermal source 7 is started working, in indoor four control heat exchangers, 5 hot-water coil pipes delivered to catalyst carrier by water pump 6, under the effect of indoor four control heat exchangers, 5 blower fans with the room air heat exchange.
During refrigeration: when a certain indoor four control heat exchangers are worked, corresponding compressor 1 work, the high-temperature high-pressure refrigerant gas process pipeline 8 of discharging is to four-way change-over valve 2, transfer to outdoor heat exchanger 3 by four-way change-over valve 2 commutations through pipeline 9, be condensed into to the outdoor air heat release by outdoor heat exchanger 3 behind the liquid of HTHP through pipeline 10, to throttle mechanism 4, transfer to the cold-producing medium coil pipe of indoor four control heat exchangers 5 after by the throttling of throttle mechanism 4 through pipeline 11, flow back to four-way change-over valve 2 through pipeline 12 after evaporation becomes gas after absorbing the room air heat under the effect of the blower fan of four control heat exchangers 5, the commutation of process four-way change-over valve 2 is got back to compressor 1 at last only to pipeline 13.
When heating: when a certain indoor four control heat exchangers are worked, corresponding compressor 1 work, the refrigerant gas of discharging HTHP arrives four-way change-over valve 2 through pipeline 8, transfer to the cold-producing medium coil pipe 5-1 of indoor four heats exchange of heat pipe 5 then through pipeline 12 by four-way change-over valve 2 commutations, after being condensed into the liquid of HTHP, the room air heat release arrives throttle mechanism 4 under the fan action of indoor four control heat exchangers 5 through pipeline 11, after passing through the throttling of throttle mechanism 4, arrive outdoor heat exchanger 3 through pipeline 10, become gas through evaporation behind the outdoor heat exchanger 3 absorption chamber outer air heats and flow back to four-way change-over valve 2, make cold-producing medium get back to compressor 1 through pipeline 13 in commutation through four-way change-over valve 2 through pipeline 9.
Winter heat supply: the heat that provides by other thermals source 7, enter water pump 6 by pipeline 14, deliver to the hot-water coil pipe 5-2 of indoor four control heat exchangers 5 then by water pump 6 process pipelines 15, after heat exchange under the effect of indoor four control heat exchangers 5, get back to other thermals source 7 through pipeline 16.
