Abstract
The utility model relates to a partial heat recovery multi-connected air-conditioner unit comprising a compressor, an oil-water separator, a water side heat exchanger, a wind side heat exchanger, an indoor machine, a refrigerating system accessory and a connecting pipeline, wherein a four-way valve is additionally arranged behind the water side heat exchanger, and simultaneously a group of heat recovery devices are additionally arranged in a cavity body of the water side heat exchanger, and are provided with water inlets and water outlets; when the wind side heat exchanger is in working and the water side heat exchanger does not work, the refrigerating agent can be controlled by the four-way valve to pass through the wind side heat exchanger so as to realize the refrigeration or heating of the running of the unit; when both heat exchangers simultaneously work, as the cavity body of the water side heat exchanger is internally and additionally provided with the group of heat recovery devices and the heat recovery devices are provided with the water inlets and the water outlets, water can be heated to realize partial heat recovery; therefore, the partial heat recovery multi-connected air-conditioner unit can provide high-temperature life hot water, and is energy-saving.
Description
Technical field
The utility model relates to a kind of portion of hot and reclaims VRF Air Conditioning System.
Background technology
Conventional refrigeration unit is formed a refrigeration cycle by compressor, condenser, evaporimeter, refrigeration system annex and connecting line etc., this unit can only provide cold air in summer, and its heat of discharging then adopts cooling water by cooling tower heat to be entered atmosphere.For energy savings better, reduce operating cost, wish that all this unit can also gratis provide a large amount of domestic hot-waters to come for people to use in refrigeration.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of energy savings, can provide the portion of hot of thermobiosis hot water to reclaim VRF Air Conditioning System.The utility model is achieved through the following technical solutions:
A kind of portion of hot of the present utility model reclaims VRF Air Conditioning System, comprises compressor, oil eliminator, water-side heat, air side heat exchanger, indoor set, refrigeration system annex and connecting line; Cross valve of addition behind water-side heat is set up one group of heat reclamation device again simultaneously in the water-side heat cavity, described heat reclamation device is provided with water inlet and delivery port.
As preferably, described compressor comprises digital compressor and constant speed compressor.
Portion of hot of the present utility model reclaims VRF Air Conditioning System, because cross valve of addition behind water-side heat is when air side heat exchanger work, when water-side heat is not worked, can control cold-producing medium by air side heat exchanger by cross valve, the realization unit operation freezes or heats; When two heat exchangers were worked simultaneously, owing to set up one group of heat reclamation device in the water-side heat cavity, described heat reclamation device was provided with water inlet and delivery port, water can be heated, thereby realize that portion of hot reclaims.Therefore, it can provide thermobiosis hot water, can energy savings.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 reclaims the schematic diagram of VRF Air Conditioning System for the utility model portion of hot.
The specific embodiment
As shown in Figure 1, a kind of portion of hot of the present utility model reclaims VRF Air Conditioning System, comprises compressor, oil eliminator O/S, water-side heat HEX_4, air side heat exchanger HEX_1, indoor set INDOOR UNIT, refrigeration system annex and connecting line; Cross valve 4WV_a of addition behind water-side heat HEX_4, in water-side heat HEX_4 cavity, set up simultaneously one group of heat reclamation device (not shown) again, described heat reclamation device is provided with water inlet WATER_IN and delivery port WATER_OUT, can be used for entering cold water, output hot water; It can provide thermobiosis hot water, can energy savings.In the present embodiment, described compressor comprises digital compressor Dig and constant speed compressor Fix1.
Portion of hot of the present utility model reclaims VRF Air Conditioning System, because cross valve 4WV_a of addition behind water-side heat HEX_4, when air side heat exchanger HEX_1 work, when water-side heat HEX_4 does not work, can control cold-producing medium by air side heat exchanger HEX_1 by cross valve 4WV_a, the realization unit operation freezes or heats; When two heat exchangers were worked simultaneously, owing to set up one group of heat reclamation device in water-side heat HEX_4 cavity, described heat reclamation device was provided with water inlet WATER_IN and delivery port WATER_OUT, water can be heated, thereby realize that portion of hot reclaims.Therefore, it can provide thermobiosis hot water, can energy savings.
The foregoing description; it is an example of the present utility model; be not to be used for limiting enforcement of the present utility model and interest field, all or technical schemes of being equal to identical with the described content of the utility model claim all should be included in the utility model protection domain.
