Description
Technical field
This utility model relates to a kind of carbon dioxide air-conditioning device, particularly relates to a kind of wind and water combined air-conditioning device of carbon dioxide.
Background technology
Critical parameters (the critical temperature t of carbon dioxidec=31.06 DEG C, pc=7377.65kPa) determine mode and basic feature that carbon dioxide heat-pump circulation should adopt.Due to the critical temperature that it is relatively low, time during cooling in summer by the restriction of ambient temperature and Winter heat supply, the needs of hot water temperature, determine Carbon Dioxide Application when art of heat pumps, should adopt the mode of trans critical cycle.Due to the characteristic of its trans critical cycle, have in providing domestic hot-water for warming up and surmount the conventional hot pump performance of freon.Simultaneously carbon dioxide is natural refrigerant, and the destruction of ozone layer and greenhouse effect are gathered effect, is almost negligible.
At present, carbon dioxide air source heat pump also begins to for heating, but hot water is first made all through source pump, then hot water passes into radiator again, in fan coil or the end equipment such as air conditioning unit, heated by the heat exchange of wind Yu water, and the minimum return water temperature of all hot water heating modes is all more than 35 DEG C, exceed the critical temperature of carbon dioxide working medium, if heating backwater is passed directly in two sample carbon source pump, its heating efficiency can be non-normally low, even run difficulty, at present, have tried to adopt following several ways to solve problem above, a kind of mode is by installing a set of water-loop heat pump additional at hot water side, source pump is entered back into after end return water temperature is down to the inflow temperature meeting source pump.Another mode is to change water-loop heat pump into heat exchanger, and by return pipe and refrigerant pipe heat exchange, both the above mode is very limited to the lifting effect of carbon dioxide heat-pump unit heating efficiency.

Detailed description of the invention
Referring to drawings and the specific embodiments, the wind and water combined air-conditioning device of carbon dioxide of the present utility model is described further.Following each embodiment is merely to illustrate this utility model and is not limitation of the utility model.
Fig. 1 is the structural representation of the wind and water combined air-conditioning device of carbon dioxide of the present utility model.As shown in Figure 1, the wind and water combined air-conditioning device of carbon dioxide of the present utility model, including compressor the 5, first heat-exchanger rig discharged after being compressed by carbon dioxide coolant, the second heat-exchanger rig, throttling arrangement, switching valve 4, air-water heat exchanger 11 and refrigerant tubing 6.Compressor 5, switching valve the 4, first heat-exchanger rig, throttling arrangement the 3, second heat-exchanger rig and air-water heat exchanger 11 are connected into cold-producing medium closed cycle loop by refrigerant tubing 6.Carbon dioxide coolant is filled in refrigerant tubing 6.
First heat-exchanger rig includes the first finned heat exchanger 1 and the first blower fan 2 connected in groups.
Second heat-exchanger rig includes air inlet the 9, second finned heat exchanger the 8, second blower fan 7 and the air outlet 10 that connect in groups successively.Second finned heat exchanger 8 is connected in series with air-water heat exchanger 11.
Water inlet pipe 12 is connected with the water inlet of air-water heat exchanger 11, and outlet pipe 13 is connected with the outlet of air-water heat exchanger 11, is full of recirculated water in water inlet pipe 12 and outlet pipe 13.
The operation principle of carbon dioxide of the present utility model wind and water combined air-conditioning device is as follows:
Compressor, switching valve, the first finned heat exchanger, the second finned heat exchanger, throttling arrangement, air-water heat exchanger, refrigerant tubing are arranged in series, by the switching valve on refrigerant tubing, it is achieved different operational modes:
When winter needs heat supply, by changing the direction of switching valve, make the carbon dioxide coolant of High Temperature High Pressure from compressor out after, first flow through air-water heat exchanger, heat exchange is carried out with the recirculated water in water inlet pipe and outlet pipe, make high-temperature-hot-water and send into the room needing heating, carbon dioxide coolant becomes time High Temperature High Pressure, pass through the second finned heat exchanger, and by opening the second blower fan, Cryogenic air is made to enter from air inlet, high temperature air is become after flowing through the carbon dioxide coolant heat exchange of the second finned heat exchanger and time High Temperature High Pressure, discharge from air outlet, sending into needs the room of heating to heat；And carbon dioxide coolant enters in throttling arrangement after becoming cryogenic high pressure, the first finned heat exchanger is entered back into after becoming low-temp low-pressure, and by opening the first blower fan, make outdoor air flow through the first finned heat exchanger and with the carbon dioxide coolant heat exchange of low-temp low-pressure after become Cryogenic air and enter outdoor again, and after the heat of carbon dioxide coolant absorption chamber outer air, flow back to again in compressor, form a heating cycle.
nullWhen needing summer to freeze，By changing the direction of switching valve，Make the carbon dioxide coolant of High Temperature High Pressure from compressor out after，First flow through the first finned heat exchanger，And by opening the first blower fan，Make outdoor air flow through the first finned heat exchanger and with the carbon dioxide coolant heat exchange of High Temperature High Pressure after become high temperature air and enter outdoor again，And carbon dioxide coolant enters in throttling arrangement after becoming cryogenic high pressure after discharging heat to outdoor air，Become low-temp low-pressure and enter back into the second finned heat exchanger，And by opening the second blower fan，High temperature air is made to enter from air inlet，Cryogenic air is become after flowing through the carbon dioxide coolant heat exchange of the second finned heat exchanger and low-temp low-pressure，Discharge from air outlet，Send into and need the room of refrigeration to carry out cooling，Carbon dioxide coolant becomes time low-temp low-pressure，Flow into air-water heat exchanger again，Heat exchange is carried out with the recirculated water in water inlet pipe and outlet pipe，Make low-temperature cold water and send into the room needing cooling，Carbon dioxide coolant flows back in compressor again，Form one for SAPMAC method.
Existing carbon dioxide air source heat pump first makes hot water owing to adopting, and then passes in radiator, fan coil or the end equipment such as air conditioning unit again, is heated by the heat exchange of wind Yu water, and its heating efficiency is relatively low, also cannot popularization and application.And air-water heat exchanger and the second finned heat exchanger are connected in series by this device, again by wind and finned heat exchanger direct heat transfer, high-temperature-hot-water can be made, return water temperature is without being down to below carbon dioxide critical temperature, also can overcome the disadvantages that air-water heat exchanger causes the problem that carbon dioxide air-conditioning device heating efficiency is low because return water temperature is too high, it is achieved hot blast and hot-water combined supplying effect.The wind and water combined air-conditioning device of carbon dioxide of the present utility model, when solving current carbon dioxide air source heat pump for heating, not only due to the return water temperature problem that the heating efficiency that causes is too low higher than carbon dioxide critical temperature, particularly there is large space hot-air heating but also have the place of hot water heating demand to provide a kind of practical energy saving and environment friendly heating plant for north cold area.
