Due to the technical scheme of additionally arranging the second heat exchanger and the water storage device in the water source multi-connected air-conditioning unit, a heat recovery work mode is added, and in the heat recovery work mode, condensation heat is used for heating water stored in the water storage device, hot water is supplied to users to be used, and accordingly condensation heat waste is avoided.
Description
Technical field
The present invention relates to air-conditioning technical field, be specifically related to a kind of heat recovery water source VRF Air Conditioning System.
Background technology
Conventional water source VRF Air Conditioning System comprises the assemblies such as compressor, oil eliminator, gas-liquid separator, indoor set and heat exchanger, said modules consists of a kind of refrigeration cycle, the cold-producing medium that compressor is discharged is through heat exchanger and after recirculated water heat release wherein, by indoor set from indoor absorption heat.
Cold-producing medium enters into recirculated water through the heat of over-heat-exchanger transmission, and recirculated water communicates with atmosphere by cooling tower.For the user, recirculated water belongs to addle useless.As seen, cold-producing medium has been wasted through the condensation heat of over-heat-exchanger transmission.If this partial condensation recuperation of heat can be used, great energy-saving significance will be arranged.
Summary of the invention
The embodiment of the invention provides a kind of heat recovery water source VRF Air Conditioning System, can waste the problem of condensation heat to solve existing air-conditioning unit.
A kind of heat recovery water source VRF Air Conditioning System comprises:
Compressor, oil eliminator, gas-liquid separator, indoor set, First Heat Exchanger, and refrigeration system annex, described oil eliminator is connected with the first cross valve, described the first heat exchanger is connected with the second cross valve, and described the first cross valve is connected with the second cross valve, also comprises:
With the second heat exchanger that described the second cross valve is connected, described the second heat exchanger is connected with water storage device.
The embodiment of the invention adopts the technical scheme of setting up the second heat exchanger and water storage device in the water source VRF Air Conditioning System, the heat recovery water source VRF Air Conditioning System that provides has been increased under the recuperation of heat mode of operation, under this mode of operation, condensation heat is used to heat the water of storing in the water storage device, provide hot water to use to the user, thereby, avoided condensation heat to be wasted.
Description of drawings
Fig. 1 is structure and the principle schematic of the heat recovery water source VRF Air Conditioning System of the embodiment of the invention.
The specific embodiment
Embodiment one,
As shown in Figure 1, the embodiment of the invention provides a kind of heat recovery water source VRF Air Conditioning System, comprising:
Compressor, oil eliminator, gas-liquid separator, indoor set, First Heat Exchanger, and refrigeration system annex, described oil eliminator is connected with the first cross valve, described the first heat exchanger is connected with the second cross valve, and described the first cross valve is connected with the second cross valve, also comprises:
With the second heat exchanger that described the second cross valve is connected, described the second heat exchanger is connected with water storage device.
Wherein, the refrigeration system annex comprises needle-valve, stop valve, filter, high-low pressure sensor, high-voltage switch gear, electric expansion valve etc.
The heat recovery water source VRF Air Conditioning System that the embodiment of the invention provides has two kinds of mode of operations:
A kind of is the mode of operation identical with common water source VRF Air Conditioning System, is called normal mode of operation; A kind of is that the present embodiment is exclusive, and mode of operation that can recovering condensing heat is called the recuperation of heat mode of operation.
Under normal mode of operation, First Heat Exchanger work, the second heat exchanger is not worked, and the cold-producing medium that compressor is discharged passes through the first cross valve, the second cross valve successively, First Heat Exchanger, indoor set behind the gas-liquid separator, is got back in the described compressor, at this moment, condensing agent flow direction such as figure hollow core arrow are indicated.
Under the normal mode of operation, when condensing agent passes through First Heat Exchanger, heat transferred recirculated water, recirculated water links to each other with atmosphere by cooling tower, and dissipation of heat is in atmosphere.
Under the recuperation of heat mode of operation, First Heat Exchanger is not worked, the first cross valve, the second cross valve are passed through in the second heat exchanger work, the cold-producing medium that compressor is discharged successively, the second heat exchanger, indoor set behind the gas-liquid separator, is got back in the described compressor, at this moment, filled arrows indication among condensing agent flow direction such as the figure.
Under the recuperation of heat work mode of operation, when condensing agent passed through the second heat exchanger, the water of storing in the heat transferred water storage device with the water heating, can provide hot water for the user.Water storage device can also be connected with water pump, and in the time need to heating to the water of water storage device, pump working makes water flow and the circulation in the second heat exchanger, thereby reaches the heat exchange purpose.
The heat recovery water source VRF Air Conditioning System of the embodiment of the invention, control by stream, for example, utilize the current method of the second cross valve control cold-producing medium, can realize under different mode of operations, make cold-producing medium respectively by the first or second heat exchanger, easily realize the switching between two mode of operations.
To sum up, the embodiment of the invention provides a kind of heat recovery water source VRF Air Conditioning System, the technical scheme of the second heat exchanger and water storage device is set up in employing in VRF Air Conditioning System, the heat recovery water source VRF Air Conditioning System that provides has been increased under the recuperation of heat mode of operation, under this mode of operation, condensation heat is used to heat the water of storing in the water storage device, provides hot water to use to the user, thereby, avoided condensation heat to be wasted.
The above heat recovery water source VRF Air Conditioning System that the embodiment of the invention is provided is described in detail, and understands method of the present invention and core concept thereof but the explanation of above embodiment just is used for help, should not be construed as limitation of the present invention.Those skilled in the art are in the technical scope that the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
