Abstract
The utility model relates to a total heat recovery multi-connected air conditioning unit which comprises a compressor, an oil separator, a water-side heat exchanger, an air-side heat exchanger, an indoor unit, refrigerating system accessories and a connecting pipeline. A first four-way valve is additionally arranged behind the oil separator and a second four-way valve is additionally arranged behind the first four-way valve. The water-side heat exchanger and the air-side heat exchanger are connected on the second four-way valve. A heat recovery device is additionally arranged in the chamber of the water-side heat exchanger and is provided with a water inlet and a water outlet. When the air-side heat exchanger works and the water-side heat exchanger does not work, refrigerant can be controlled through the four-way valve to pass through the air-side heat exchanger and the refrigerating or heating of the unit is realized; and when the air-side heat exchanger does not work and the water-side heat exchanger works, the refrigerant can be controlled through the four-way valve to pass through the water-side heat exchanger, the water is heated and the total heat recovery is realized. Thereby, the utility model has the advantages that the high-temperature domestic hot water can be provided and the energy can be saved.
Description
Technical field
The utility model relates to a kind of complete heat-recovery multi-connected air-conditioning unit.
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, and the complete heat-recovery multi-connected air-conditioning unit of thermobiosis hot water can be provided.The utility model is achieved through the following technical solutions:
A kind of complete heat-recovery multi-connected air-conditioning unit of the present utility model comprises compressor, oil eliminator, water-side heat, air side heat exchanger, indoor set, refrigeration system annex and connecting line; Addition first cross valve behind oil eliminator, and behind first cross valve addition second cross valve, described water-side heat all is connected on second cross valve with air side heat exchanger, simultaneously set up one group of heat reclamation device again 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.
Complete heat-recovery multi-connected air-conditioning unit of the present utility model, because two cross valves of addition before water-side heat and air side heat exchanger, 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, thereby the realization unit operation freezes or heats; When air side heat exchanger is not worked, during water-side heat work, can control cold-producing medium by cross valve and pass through water-side heat, owing in the water-side heat cavity, set up one group of heat reclamation device, described heat reclamation device is provided with water inlet and delivery port, water can be heated, thereby realize whole recuperations of heat.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 is the schematic diagram of the complete heat-recovery multi-connected air-conditioning unit of the utility model.
The specific embodiment
As shown in Figure 1, a kind of complete heat-recovery multi-connected air-conditioning unit of the present utility model comprises compressor, oil eliminator O/S, water-side heat HEX_3, air side heat exchanger HEX_1, indoor set INDOOR UNIT, refrigeration system annex and connecting line; The addition first cross valve 4WV_a behind oil eliminator O/S, and behind the first cross valve 4WV_a addition second cross valve 4WV_b, described water-side heat HEX_3 all is connected on the second cross valve 4WV_b with air side heat exchanger HEX_1, in water-side heat HEX_3 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.
Complete heat-recovery multi-connected air-conditioning unit of the present utility model, because two cross valves of addition before water-side heat HEX_3 and air side heat exchanger HEX_1, when air side heat exchanger work, when water-side heat is not worked, can control cold-producing medium by air side heat exchanger HEX_1 by cross valve, cross valve can also be controlled the flow direction of cold-producing medium, thereby the realization unit operation freezes or heats; HEX_1 does not work when air side heat exchanger, during water-side heat HEX_3 work, can control cold-producing medium by water-side heat HEX_3 by cross valve, owing in water-side heat HEX_3 cavity, set up one group of heat reclamation device, described heat reclamation device is provided with water inlet WATER_IN and delivery port WATER_OUT, water can be heated, thereby realize whole recuperations of heat.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.
