Background technology
Temperature, humidity independence control technology mainly are that airborne humidity load and sensible heat load are controlled respectively, reach healthy, comfortable, environmental protection and energy-conservation effect.In the prior art, temperature, humidity independence control technology are mainly used in the summer air-conditioning system.Its application mode comprises three types: a kind of is low temperature cold source with single temperature, and a part is directly used in new blower fan group, handles the humidity load of air; A part is produced high temperature cold water by Intermediate Heat Exchanger in addition, and the cooling that is used for air by indoor dry type end is handled, as shown in Figure 1.Another kind is to adopt the new blower fan group of solution dehumidification to handle the humidity load of air, and the cooling of adopting the high temperature low-temperature receiver to be used for air is simultaneously handled, as shown in Figure 2.The third mode such as Chinese patent application number are 200720195921.3 " a kind of humiture independent regulation air-conditioning system based on the two low-temperature receivers of high low temperature ", it is that a kind of employing low temperature cold source carries out freeze drying, the all-air system that adopts the high temperature low-temperature receiver to lower the temperature then, as shown in Figure 3.For first kind of mode, its shortcoming is the system energy consumption height, and main cause is a handpiece Water Chilling Units when producing water at low temperature (7 ℃), and its Energy Efficiency Ratio is lower more than 20% than the handpiece Water Chilling Units Energy Efficiency Ratio of producing idle call high-temperature water (18 ℃); In addition, it is by the high temperature cold water of Intermediate Heat Exchanger with 7 ℃ water at low temperature heat exchange to 18 ℃, and the grade of cold energy descends very big, and the efficiency loss is big, though system is warm and humid sub-control system, does not bring into play the power savings advantages of warm and humid sub-control system.For the second way, the principle of solution dehumidification is to utilize the absorption of solution concentration difference realization to water in air vapour, and then the concentrated principles of chemistry of heat, this mode major defect is that the volume of the new blower fan group of solution dehumidification is bigger, the installing space demand is big, and the solution of open type circulation may make contaminated aqueous solution to new wind, thereby is not used widely as yet.The third mode, it mainly is the processing at the hot humidity load in summer, the heating in winter must be established a cover system in addition and be finished, and because the processing temperature difference of high temperature cold water is limited, the air output that needs is a lot of greatly than the conventional system air quantity, therefore, employing all-air system pattern can significantly increase the power of pressure fan, reduces the operational energy efficiency of whole air-conditioning system.
Summary of the invention
At above-mentioned problems of the prior art, the purpose of this utility model provides the aircondition that a kind of temperature and humidity that adopts two low-temperature receivers is independently controlled.This device is regulated the sensible heat load and the humidity load of air respectively, has that energy consumption is low, equipment volume is little, an operation characteristics of high efficiency.
In order to reach the foregoing invention purpose, the technical solution of the utility model realizes as follows:
The aircondition that a kind of temperature and humidity that adopts two low-temperature receivers is independently controlled, it comprises latent heat load treatment facility and sensible heat load treatment facility.Its design feature is that described latent heat load treatment facility is made up of with many that link to each other with cold water/source pump by pipeline new blower fan groups cold water/source pump.The sensible heat load treatment facility is made up of with many dry types that link to each other with the high temperature cold water unit by pipeline are terminal high temperature cold water/source pump.
In above-mentioned aircondition, be respectively equipped with water circulating pump on the outlet conduit of described cold water/source pump and high temperature cold water/source pump.
In above-mentioned aircondition, described cold water/source pump adopts water resource heat pump, earth source heat pump or net for air-source heat pump units.
In above-mentioned aircondition, terminal dry type air-conditioning unit or dry-type fan coil or the cold/heat radiation end of adopting of described dry type.
The utility model adopts high temperature cold water/source pump in conjunction with the terminal sensible heat load of handling air of dry type respectively owing to adopted said structure, realizes the cooling or the intensification of air; Adopt the cold/heat source of conventional cold water/source pump, handle the humidity load of new wind and the humidity load of room air, realize dehumidifying or humidification air as new blower fan group.The utility model both can have been brought into play the efficiency of air-conditioning/heat pump main frame, can make full use of the advantage of dry type end again, realized the efficient operation of aircondition, the health of assurance room air and comfortable.Compare with prior art, the utility model can significantly improve the air-conditioner host operational energy efficiency, improves system's operational energy efficiency.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
