Background technology
Air-conditioning is one of topmost cooling system, is widely used on house, commercial location and the vehicles.Air-conditioningThe moisture of in the air can be led to separate out while cooling, this phenomenon is referred to as condensation, and the moisture of precipitation is also referred to asFor condensed water.
Under normal circumstances, condensed water can directly be discharged, and not only causes the waste of water resource it is often more important that causing energyThe waste in source: because the temperature of condensed water is very low, contain more cooling power, these energy are directly arranged with condensed waterPut, be unfavorable for energy-conservation.
In order to make full use of the refrigerating capacity of condensed water, in prior art, occur in that multiple condensation water recovery and use systems,For example: Application No. " cn201220721940.6 " discloses a kind of " a kind of condensed water apparatus for energy recovery ", this condensation water energyEnergy recovery device includes the first condensed water conveyance conduit, water storage box, immersible pump, the second condensed water conveyance conduit, heat exchanger andThree condensed water conveyance conduits.One end of first condensed water conveyance conduit is connected with the condensed water outlet of Air conditioner box, anotherEnd is connected with water storage box, for being delivered to condensed water in water storage box；Water storage box is used for storing condensed water；Immersible pump one end withWater storage box is connected, and the other end is connected with the second condensed water conveyance conduit, for extracting condensed water from water storage box and being delivered toIn second condensed water conveying management；Second condensed water conveyance conduit is connected with heat exchanger, for condensed water is delivered to heat exchangeIn device；Heat exchanger is connected with the 3rd condensed water conveyance conduit, for following the energy of condensed water with outdoor fresh air or/and interiorRing wind facies exchanges.
This condensed water apparatus for energy recovery is installed at the specified air channel in building air-conditioning box, for example, is installed on groupAt the fresh air inlet of box-like Air conditioner box, or/and, it is installed at the indoor circulation wind return air inlet of assembled air-conditioner cabinet.Make newWind or/and indoor circulation wind pass through heat exchanger, as such, it is possible to new to high temperature in porch by the condensed water within heat exchangerWind or/and indoor circulation wind are tentatively lowered the temperature, thus reducing fresh air or/and the temperature of indoor circulation wind entrance fan coilDegree, such that it is able to make air-conditioning reduce power consumption in refrigeration, improves energy use efficiency, has reached the purpose of saves energy.
