The utility model also proposes a kind of central air conditioner system of using above-mentioned condensed water heat-recovery circulating system, comprise handpiece Water Chilling Units, at least one group of fresh air processor group, air-treatment unit and many typhoons coiler, wherein, also comprise: the condensate draining pipe road that is connected with condensate pipe with many typhoons coiler with the heat exchanger of described fresh air processor group, the condensed water return water tank, the condensed water water supply line, with the precool heat exchanger device that is arranged in the described fresh air processor group, described condensate draining pipe road is introduced the condensed water that reclaims in the condensed water return water tank, the outlet of described condensed water return water tank is introduced described precool heat exchanger device by condensed water circulating pump and condensed water water supply line with condensed water, and new wind carries out heat exchange with precool heat exchanger device and heat exchanger successively.
Compared with prior art, the condensed water recuperation of heat cyclic utilization system of the utility model design, the condensed water that air-conditioning system is produced is collected in the condensed water return water tank, after the pressurization of condensed water circulating pump, send into the preliminary treatment surface cooler of fresh air processor group again, utilize cryogenic condensation water about 16 ℃ to the processing of lowering the temperature in advance of outdoor 35 ℃ of new wind sending into, lowered the temperature by the master meter cooler again through pretreated new wind, dehumidification treatments, condensed water emits behind the heat that absorbs new wind again, can fully reclaim the contained cold of condensed water, avoid the waste of cold, reduce the refrigeration duty of air-conditioning system simultaneously, reduce power consumption, energy savings.
Description of drawings
Fig. 1 is the schematic diagram of existing central air-conditioning condensed water drainage system;
Fig. 2 is the system schematic of utility model preferred embodiment.
The specific embodiment
Below in conjunction with drawings and Examples utility model is described in detail.
Fig. 1 comprises fresh air processor group 1, air-treatment unit 11, fan coil 2, condensate draining pipe road 4 for existing central air-conditioning condensed water drainage system schematic diagram.16 ℃ of left and right sides condensed waters that heat exchanger 3 process chamber inner air and outer air and new wind produce in the fan coil of central air conditioner system, air-treatment unit and the fresh air processor group collect in the ponding dish 32, conflux through outlet pipe 31, horizontal pipeline then and adopt standpipe into this pipeline of condensate draining pipe road 4() concentrate directly and discharge, the contained cold of condensed water does not obtain any utilization, wastes energy.
As shown in Figure 2, the condensed water heat recovery system that the utility model proposes comprises: condensate draining pipe road 4, condensed water return water tank 5, the condensed water water supply line 6 that is connected with condensate pipe with many typhoons coiler 2 with the heat exchanger 3 of at least one group of fresh air processor group 1 and be arranged on precool heat exchanger device 7 in the described fresh air processor group.Condensate draining pipe road 4 is introduced the condensed water that reclaims in the condensed water return water tank 5, the outlet of condensed water return water tank is introduced precool heat exchanger device 7 by condensed water circulating pump 8 and condensed water water supply line 6 with condensed water, and new wind carries out heat exchange with precool heat exchanger device and heat exchanger successively.
The utility model also proposes a kind of central air conditioner system, and this system comprises handpiece Water Chilling Units, at least one group of new blower fan group, air-treatment unit and many typhoons coiler and condensed water heat recovery system.
The fan coil 2 of central air conditioner system, 16 ℃ of left and right sides condensed waters that air-treatment unit 11 and fresh air processor group 1 process chamber inner air and outer air and new wind produce, through ponding dish 32, outlet pipe 31, horizontal pipeline confluxes into condensate draining pipe road 4, concentrate and enter in the condensed water return water tank 5, condensed water in the condensed water return water tank is condensed and is sent into again in the precool heat exchanger device 7 of fresh air processor group 1 after water-circulating pump 8 pressurizes, utilize condensed water to the preliminary treatment of lowering the temperature of 35 ℃ new wind, condensed water is owing to the heat temperature that absorbs new wind is elevated to about 26 ℃, drainpipe 71 through the precool heat exchanger device discharges again, thus, the contained cold of cryogenic condensation water has obtained sufficient recycling.The total refrigerating capacity of the new wind that fresh air processor group 1 is handled is certain, the precool heat exchanger device has been born certain cold, therefore, the cold that the chilled water heat exchanger is born reduces, thereby the overall refrigerating effect of whole central air conditioner system is reduced, effectively reduce the installed capacity of central air conditioner system, saved investment and the operation electricity charge.
