Description
The present invention relates to a kind of liquid-liquid cold/heat source apparatus that room temperature is regulated that is used for.
In the aircondition that uses at present, condenser and evaporimeter all adopt General design.Aircondition can switch condenser and evaporimeter in the use of Various Seasonal, to finish refrigeration and heating condition.But owing to adopted the condenser and the evaporimeter of General design, the shortcoming of this aircondition is: environment temperature is lower in the winter time, under subzero 10-15 ℃ situation, can't be converted to high level heat because Lowlevel thermal energy is not enough, so high level heat can't be emitted, so can not be as the thermal source operate as normal under this class aircondition situation that environment temperature is lower in the winter time.In addition, present aircondition also exists power consumption big, heat pump must be arranged on outdoor shortcoming.
In order to solve above-mentioned shortcoming, the invention provides a kind of liquid-liquid cold/heat source apparatus, can operate as normal under this liquid-liquid cold/heat source apparatus situation that environment temperature is lower in the winter time, and reliable, the efficient height, energy savings is installed and easy to operate.
To achieve these goals, the invention provides a kind of liquid-liquid cold/heat source apparatus, it comprises by compressor, condenser, liquid reservoir, device for drying and filtering, flow controller, evaporimeter and gas-liquid separator heat loop and heat exchange loop by what pipeline was connected in sequence, are filled with anti-icing fluid in heat exchange loop.
As to further improvement of the present invention, in described heat exchange loop, with condenser mutually the outlet pipe of coupling link to each other with first interface of first two-position four-way valve, its water inlet pipe links to each other with first interface of second two-position four-way valve; The water inlet pipe of air-conditioning links to each other with second interface of first two-position four-way valve, and its outlet pipe links to each other with the 4th interface of second two-position four-way valve through pump; With described evaporimeter mutually the outlet pipe of coupling link to each other with the 3rd interface of described first two-position four-way valve, its water inlet pipe links to each other with the 3rd interface of second two-position four-way valve; The water inlet pipe of solar thermal collector links to each other with the 4th interface of first two-position four-way valve, and its outlet pipe links to each other with second interface of second two-position four-way valve through pump.
As to further improvement of the present invention, be filled with working medium R22 in the loop described heating.
The advantage of liquid-liquid cold/heat source apparatus of the present invention is: the part that heats of the refrigeration of evaporimeter, condenser is all finished by two liquid circulation loops, therefore heat pump can be placed indoor; Condenser and evaporimeter are two heat exchangers according to the design of separately characteristics, running also special-purpose and need not to switch; Air conditioning terminal heats, freezes to exchange and switches by the cross valve group, so need not switch condenser and evaporimeter; Liquid line is filled with anti-icing fluid, and the required heat of evaporimeter is supplied with by the low heat energy that anti-icing fluid obtains; The humble heat energy of anti-icing fluid is provided by solar thermal collector, has enlarged the scope of application of solar energy, also uses solar energy to become possibility as thermal source with heat pump.
Below, in conjunction with the accompanying drawings liquid-liquid cold/heat source apparatus of the present invention is described further:
Fig. 1 is liquid-liquid cold/heat source apparatus of the present invention being not intended to of heating condition in the winter time.
Fig. 2 is the schematic diagram of liquid-liquid cold/heat source apparatus of the present invention at the cooling condition in summer.
Fig. 1 is the liquid-liquid cold/heat source apparatus of the present invention schematic diagram of heating condition in the winter time.Liquid-liquid cold/heat source apparatus of the present invention comprises and heats loop and heat exchange loop, wherein, by compressor 1, condenser 2, liquid reservoir 3, device for drying and filtering 4, flow controller 5, evaporimeter 6 and gas-liquid separator 7 are connected in sequence by pipeline and heat the loop.This heats loop and common air-conditioning, and refrigerator adopts, and to heat (cold) loop identical.In heating the loop, be filled with the working medium R22 that is used to heat circulation.
In heat exchange loop, be provided with two two-position four-way valves, i.e. first two-position four-way valve 8 and second two-position four-way valve 9.Wherein, with condenser 2 mutually the outlet pipe 2a of coupling link to each other with the first interface 8a of first two-position four-way valve 8, its water inlet pipe 2b links to each other with the first interface 9a of second two-position four-way valve 9; The water inlet pipe 102 of air-conditioning links to each other with the second interface 8b of first two-position four-way valve 8, and its outlet pipe 103 links to each other with the 4th interface 9d of second two-position four-way valve 9 through pump 11; With evaporimeter 6 mutually the outlet pipe 6a of coupling link to each other with the 3rd interface 8c of first two-position four-way valve 8, its water inlet pipe 6b links to each other with the 3rd interface 9c of second two-position four-way valve 9; The water inlet pipe 12b of solar thermal collector 12 links to each other with the 4th interface 8d of first two-position four-way valve 8, and its outlet pipe 12a links to each other with the second interface 9b of second two-position four-way valve 9 through pump 10.In heat exchange loop, be filled with anti-icing fluid.
It is as follows that liquid-liquid cold/heat source apparatus of the present invention heats the course of work in the winter time: the anti-icing fluid in the pipeline is heated in solar thermal collector 12 and under the effect of pump 10, sends into and evaporimeter 6 pipeline of coupling mutually through the water inlet pipe 6b of second two-position four-way valve 9.In evaporimeter 6, carry out heat exchange, with heat transferred evaporimeter 6.Low temperature anti-icing fluid after heat exchange is through outlet pipe 6a, and first two-position four-way valve 8 is proceeded circular flow and is back to solar thermal collector 12.Meanwhile, the effect of the working medium R22 in the evaporimeter 6 by evaporimeter 6 is converted into low-temp low-pressure gas and sends into gas-liquid separator 7, is admitted to compressor 1 in gas-liquid separator 7 after gas-liquid separation.Low-pressure low-temperature gas becomes high temperature and high pressure gas and is sent to condenser 2 by compressor 1.In condenser 2, the high temperature and high pressure gas of sending by compressor 1 with condenser 2 mutually the anti-icing fluid sent into of the water inlet pipe 2b of coupling carry out heat exchange, after the heat exchange, heated anti-icing fluid is through outlet pipe 2a, and the water inlet pipe 102 of first two-position four-way valve 8 and air-conditioning flows into air-conditioning and carries out the room temperature heating.Finish the outlet pipe 103 of anti-icing fluid by air-conditioning after the room temperature heating through second pump, 11, the second two-position four-way valves 9, with condenser 2 mutually the water inlet pipe 2b of coupling flow back into condenser 2.
