Description
Technical field
The present invention relates to a kind of efficient water source heat pump units of two temperature that is exclusively used in capillary radiation air-conditioning system, unit can provide the air conditioner water of two kinds of temperature simultaneously, and improves more than 30% than the efficient of traditional water source heat pump units, belongs to the highly effective energy-saving heat pump technical field.
Background technology
Capillary radiation air-conditioning system is a kind of novel air-conditioning system type, and the air-conditioning system of this form is to adopt thermal-radiating mode air conditioning area is cooled off and to heat, and replaces traditional forced convertion heat exchange form.Its biggest advantage heat exchange area is big, thereby has reduced the temperature difference of heat exchange, makes source pump in refrigeration, will temperature not fall lowly excessively, also will temperature heating De Taigao when heating.Wherein summer, chilled water temperature was higher more than 10 ℃ than conventional central air-conditioning, and winter, the hot water temperature was then low more than 10 ℃ than conventional central air-conditioning.In theory, such water temperature can make the efficient of source pump improve more than at least 30%.Yet; The greatest problem that the air-conditioning system of this kind form existed in summer is the problem of building enclosure surface, room condensation, therefore need carry out appropriate control to room wet-bulb temperature, particularly for the new wind that contains a large amount of moistures; Be transported to indoor before; Must effectively dehumidify, and the effective means of dehumidifying reduces the chilled water supply water temperature exactly, the chilled water temperature of the usefulness that dehumidifies general summer should not be higher than 7 ℃.Obviously, capillary radiation system and fresh air treatment system can not be compatible to the requirement of water temperature.Current way is by source pump the water temperature unification to be prepared into the needed temperature of VMC; Then a part directly being supplied with VMC uses; Major part is in addition then carried out adjustment through heat exchanger, it is reached resupply capillary radiation air-conditioning system after the desired temperature of capillary air-conditioning system and use.Thus, the theoretic energy saving space of capillary system will be offseted fully, thereby does not have to give full play to capillary radiation air-conditioning system in this advantage on the one hand.
Summary of the invention
In order to overcome the shortcoming of the existing water source heat pump units of capillary air-conditioning system, the present invention proposes a kind of brand-new efficient water source heat pump units of two temperature that is exclusively used in capillary radiation air-conditioning system.At first, unit has two cover refrigeration systems, and wherein a cover is used to capillary radiation air-conditioning system special-purpose air conditioner water is provided; Compare with the conventional heat pump unit; Can provide the chilled water of higher temperature summer, and the hot water of lower temperature then is provided winter, and an other cover then is used for for fresh air treatment system special-purpose air conditioner water being provided; The chilled water of lower temperature is provided summer, the hot water of higher temperature is provided winter; Secondly, the two cover shared water-cooled condensers of refrigeration system (be evaporimeter winter) are shared same set of intelligence control system, and compressor, heating power expansion valve, evaporimeter then are separate, and have the different working parameter.Control through the unified intelligence control system of a cover; Unit can independently be controlled the leaving water temperature and the cooling and warming load of two cover systems; And through the optimal design of refrigeration system and the resource-sharing of heat exchanger; Thereby can optimize utilization fully to the distinctive working condition of capillary radiation air-conditioning system, make source pump of the present invention improve more than at least 30% than the overall efficiency of traditional water source heat pump units.
Concrete technical scheme of the present invention is following:
Two overlap independently refrigeration system:
Unit involved in the present invention possesses the separate refrigeration system of two covers; Wherein a cover is used to capillary radiation air-conditioning system special-purpose air conditioner water is provided; Compare with the conventional heat pump unit, can provide the chilled water of higher temperature summer, and the hot water of lower temperature then is provided winter; An other cover then is used for for fresh air treatment system provides special-purpose air conditioner water the chilled water of lower temperature being provided summer, and the hot water of higher temperature is provided winter.Since adopt can the adaptation condition condition refrigeration system, thereby make the traditional source pump of machine performance coefficient ratio improve more than 30%.
Fig. 1 has shown the refrigeration system flow chart of unit.
Two cover independent compressed units:
Unit involved in the present invention possesses two cover compression ratios different refrigeration compressor set, and wherein one group is used to capillary system cooling and warming is provided, and has bigger refrigerating capacity, lower compression ratio and higher refrigerating efficiency; Other one group is used to VMC cooling and warming is provided, has less refrigerating capacity, higher compression ratio and the refrigerating efficiency suitable with conventional air-conditioning.
The water-cooled condenser in a double-refrigerant loop (be evaporimeter winter):
Source pump involved in the present invention disposes the water-cooled condenser in a double-refrigerant loop.The refrigerant loop of condenser is divided into two; Correspond respectively to fresh air refrigerating system and capillary air-conditioning refrigeration system, wherein the condenser of the fresh air refrigerating system condenser that is positioned at the upper reaches capillary air-conditioning refrigeration system in heat exchanger cooling medium loop then is positioned at the downstream in heat exchanger cooling medium loop.The purpose of so arranging is because the Cooling and Heat Source temperature difference of capillary system is bigger; Cause system compresses higher frequently; Its heat exchanger is positioned over the upper reaches of cooling medium; Help utilizing the cooling medium inlet temperature of lower (winter is then for higher) to reduce the condensing pressure (winter is then for improving the evaporating pressure of unit) of unit, thereby reduce the compression ratio of system, improve the efficient of new wind-heat pumping system; And because the Cooling and Heat Source temperature difference of capillary radiation system is less, therefore its heat exchanger is arranged in downstream can not produce excessive influence to efficient.So the benefit of design heat exchanger is 1) compact conformation, 2) share heat exchange area and cooling medium conveying equipment, 3) comprehensively improve the efficient of unit.
Two separate evaporimeters (be condenser winter):
Source pump involved in the present invention adopts the evaporimeter of two separate water-refrigerant heat exchange forms; The evaporimeter type is any among heat-exchangers of the plate type, shell and tube heat exchanger or the double pipe heat exchanger; Two evaporimeters have different evaporating temperatures and evaporating pressure, and corresponding to the supply water temperature of the system that is served separately.
Two separate thermal expansion systems:
Source pump involved in the present invention adopts two independently thermal expansion systems, and two expansion systems have the different coefficients of expansion, and corresponding to the evaporating temperature of the system that is served separately.
One cover intelligence control system:
Source pump involved in the present invention adopts a cover intelligence control system, is used for coordinating and controlling the work of two refrigeration systems, can monitor in real time and control leaving water temperature, the cooling load of two refrigeration systems simultaneously.Adjust timely and satisfy thereby the temperature requirement that makes system can access.
