The realization of the utility model object, functional characteristics and advantage, in connection with embodiment, are described further with reference to accompanying drawing.

The specific embodiment

Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

The utility model provides a kind of multi-online air-conditioning system that reclaims interior machine condensed water cold, see figures.1.and.2, it has disclosed an embodiment of the multi-online air-conditioning system of machine condensed water cold in the utility model recovery, in the present embodiment, this multi-online air-conditioning system comprises a plurality of interior machines unit 10, for the condensed water that collects the condensed water storage element 20 of the condensed water that interior machine unit 10 produces and condensed water storage element 20 is collected, is conveyed into the driver element 30 of interior machine unit.

Interior machine unit 10 has evaporimeter 110, heat exchanger 120, blower fan 130, temperature sensing device 140, control device 150 and water collector 160.

Evaporimeter 110 is for the air generation heat exchange with indoor, when multi-online air-conditioning system freezes, and the heat of the air of cold-producing medium in the interior evaporation of evaporimeter 110 and in absorption chamber, thus realize heat exchange.

Heat exchanger 120 has the conduit 121 of coiling, is increasing heat radiation area, and fin 122 is set on conduit 121, when condensation flow is during through heat exchanger 120, and the air generation heat exchange blowing with blower fan 130.If flow through, the temperature of the condensed water of heat exchanger 120 is lower than the temperature (environment temperature) of air, and condensed water absorbs the heat of air, and the condensed water of the heat exchanger 120 of flowing through plays cooling effect; If flow through, the temperature of the condensed water of heat exchanger 120 is higher than the temperature of indoor air; now in underload, (refrigerating capacity conventionally producing under this state is too much in corresponding interior machine unit 10; particularly at careat hour) or the state such as shutdown, condensed water absorbs the cold of air.

Blower fan 130 is for indoor air being blowed to heat exchanger 120 and evaporimeter 110, to improve the efficiency of heat exchange.

Temperature sensing device 140 is for the temperature of machine unit 10 in sensing, thereby can judge that the temperature of condensed water of inflow heat exchanger 120 is higher than the temperature (environment temperature) of indoor air or lower than the temperature of air, so judgement corresponding in machine unit 10 in high loaded process or in low load operation.

Control device 150 is magnetic valve, and it is arranged on the import of heat exchanger 120, for controlling condensed water, flows into heat exchanger 120.

Water collector 160 is arranged on the below of the outlet of evaporimeter 110 and heat exchanger 120, the condensed water carrying out after heat exchange for collecting the condensed water that evaporimeter 110 produces because of condensation and the heat exchanger 120 of flowing through.

Condensed water storage element 20 has attemperater 210 and is arranged on full water water valve 220, draining water valve 230 and the water level valve 240 on attemperater 210.Attemperater 210 is connected with the water collector 160 of interior machine unit 10, for collecting the condensed water of interior machine unit 10 condensed water producing and heat exchanger 120 heat exchange of flowing through.Full water water valve 220 is manual water valve, and it, while reaching certain value for the water level in attemperater 210 is discharged unnecessary condensed water in normally open.Draining water valve 230 is also manual water valve, and it is arranged on the bottom of attemperater 210 and in normally off, opening draining water valve 230 can be emptying by the water of attemperater 210, thereby can carry out blowdown so that it is cleared up to attemperater 210.Water level valve 240 is for the water level of sensing attemperater 210, at the water level that senses attemperater 210, during lower than the water level of water level valve 240, driver element 30 quit work.

Driver element 30 is water pump, its respectively with attemperater 210 be connected with the control device 150 that is arranged on heat exchanger 120 imports, for the condensed water of attemperater 210 is transported to heat exchanger 120, so that condensed water and indoor air carry out heat exchange.

In addition, for preventing the 10 unlatching negligible amounts in interior machine unit, in flowing into, the condensation water quantity of machine unit 10 is less, and the pressure reduction that the water yield of the condensed water that driver element 30 is carried causes when still large is excessive, between driver element 30 and condensed water storage element 20, partial pressure unit 40 is also set, this partial pressure unit 40 is differential pressure flow switches, when pressure reduction reaches certain value, differential pressure flow switches is opened, thereby the guiding of a part for the condensed water of driver element 30 outputs by differential pressure flow switches is back to condensed water storage element 20.

At above-mentioned multi-online air-conditioning system during in refrigeration mode, the heat of the air of cold-producing medium in the interior evaporation of evaporimeter 120 and in absorption chamber, effect because of condensation, the condensed water that evaporimeter 120 produces flows into water collector 160, and the attemperater 210 that the condensed water of inflow water collector 160 flows into condensed water storage element 20 along direction shown in arrow A collects.The condensed water collecting in attemperater 210 is delivered to evaporimeter 110 along direction shown in arrow B by driver element 30, when condensation flow is during through heat exchanger 120, and the air generation heat exchange blowing with blower fan 130.If flow through, the temperature of the condensed water of heat exchanger 120 is lower than the temperature of air, and condensed water absorbs the heat of air, and the condensed water of the heat exchanger 120 of flowing through plays cooling effect; If flow through, the temperature of the condensed water of heat exchanger 120 is higher than airflow temperature; now corresponding interior machine unit 10 is in states such as underload or shutdown; under this state, can there is unnecessary cold; therefore after the cold of condensed water absorption air, be back to attemperater 210, thereby condensed water plays cold, collect, shift.If open negligible amounts at interior machine 10, and the water yield of the condensed water that driver element 30 is carried is when still large, and a part for the condensed water of the output of driver element 30 is back to condensed water storage element 20 along direction shown in arrow C by partial pressure unit 40.

Because the utility model multi-online air-conditioning system is under refrigeration mode, the condensed water that evaporimeter 110 produces is collected in the below that is arranged on evaporimeter 110 by water collector 160, attemperater 210 by condensed water storage element 20 collects condensed water again, thereby can reclaim the condensed water that multi-online air-conditioning system produces; Collect in the heat exchanger 120 that the condensed water of attemperater 210 is delivered to machine unit 10 in each by driver element 30 and carry out heat exchange, thereby the cold of condensed water can be recycled, and heat exchanger 120 condensed waters that are delivered to machine unit 10 in each can absorb underload interior machine unit 10 residue cold and be transferred to machine unit 10 in other, thereby the object that realizes recovery and the transfer of cold, has improved energy utilization rate.

These are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
