Detailed Description

The present invention will be further illustrated by the following specific examples, which are carried out on the premise of the technical scheme of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, an air conditioning system for realizing the supply of cold and heat to a basement on a building in summer in a villa comprises a heat pump 1, an upstairs region tail end 2, a basement region tail end 3 and a water loop heat pump 4 arranged in a basement region, wherein the water loop heat pump 4 adopts a small water loop heat pump and is connected in series on a pipeline leading from the heat pump to the basement region, one path of a water outlet 11 of the heat pump 1 is connected with the upstairs region tail end 2 and returns to a water inlet 12 of the heat pump 1 from the upstairs region tail end 2 to form a loop of the heat pump 1 and the upstairs region tail end 3; the other path of the water outlet 11 of the heat pump 1 is connected with the tail end 3 of the basement region through the water-ring heat pump 4 and returns to the water inlet 12 of the heat pump 1 from the tail end 3 of the basement region through the water-ring heat pump 4, so that a loop of the heat pump 1 and the tail end 3 of the basement region is formed. A plurality of upstairs area terminals 2 and basement area terminals 3 can be arranged and are connected with the heat pump 1 through branch pipes and main pipes.

The forms of the terminal 2 of the upstairs area and the terminal 3 of the basement area are not limited, and the terminal can be a fan coil, a floor heater or a capillary tube. The heat pump 1 adopts an air source heat pump or a ground source heat pump. When the air source heat pump is in operation, the evaporator absorbs heat from ambient heat energy in the air to evaporate a heat transfer working medium, the pressure and the temperature of the working medium steam are increased after the working medium steam is compressed by the compressor, and when high-temperature steam passes through a special annular pipe adhered to the outer surface of the water storage tank, the condenser is condensed into liquid to transfer the heat to water in the water storage tank of the air source heat pump. The ground source heat pump is a high-efficiency energy-saving air conditioning device which can supply heat and refrigerate by utilizing shallow geothermal resources (also called geothermal energy, including underground water, soil or surface water and the like). The ground source heat pump realizes the transfer from low-temperature heat energy to high-temperature heat energy by inputting a small amount of high-grade energy (such as electric energy). The geothermal energy is respectively used as a heat source for heat supply of the heat pump in winter and a cold source for refrigeration in summer, namely, in winter, the heat in the geothermal energy is taken out, and the geothermal energy is supplied for indoor heating after the temperature is increased; in summer, indoor heat is taken out and released to the ground energy, and the ground source heat pump saves more energy.

The pipelines outside the water inlet 12 and the water outlet 11 of the heat pump 1 are both provided with a temperature sensor 5 and a pressure gauge 6, the temperature and the pressure of the inlet water and the outlet water of the heat pump 1 are detected, and the control system is convenient to adjust. Still all be provided with automatic vent valve 7 and ball valve 8 on the pipeline of water inlet 12 and delivery port 11 of heat pump 1, because numerous harmful effects that gas such as hydrogen, oxygen etc. that water released when heating brought can damage the system and reduce the thermal effect, these gases can produce many harmful results if can not in time arrange to fall, for example: corrosion due to oxidation; forming an air bag in the radiator; hot water circulation is not smooth and balanced, so that some radiators are not hot locally; noise when the pipeline is running with air; the vortex-air phenomenon of the circulating pump and the like, the automatic exhaust valve 7 can timely discharge waste gas in the system at regular time, and the stable and efficient operation of the air-conditioning system is ensured.

The water filter 9 is arranged outside the water inlet 12 of the heat pump 1, so that impurities in the pipeline are prevented from entering the heat pump to damage the heat pump, meanwhile, the maintenance frequency can be reduced, the water filter 9 is also arranged outside the inlets of the terminal 2 of the upstairs area and the terminal 3 of the basement area, so that the impurities in the pipeline are prevented from entering the coil pipe and the capillary pipe at the terminal, the coil pipe or the capillary pipe is prevented from being blocked, and particularly, the capillary pipe is small in diameter and difficult to maintain due to the adoption of the terminal of the capillary pipe.

The regional water ring heat pump 4 of basement and upstairs regional end 2 are the intercommunication, can carry out the exchange of hot and cold water, with the regional water ring heat pump 4's of basement energy transport to upstairs region, the utility model discloses can have multiple mode:

the first method comprises the following steps: when an upstairs area is refrigerated and a basement area is heated, the heat pump 1 starts a refrigeration mode, meanwhile, part of cold water is connected to the water-loop heat pump 4, the water-loop heat pump 4 starts a heating mode, the part of water is used for supplying heat to the secondary side of the basement area, and meanwhile, the cold energy is carried to the primary side to cool the water on the building.

And the second method comprises the following steps: when the cold and heat loads of the upstairs area and the basement area are equivalent, the air source heat pump or the ground source heat pump can keep the indoor temperature and humidity of the whole villa without being started, and the energy consumption is reduced. Even when the difference between the cold and hot loads of the building and the basement is large, the starting time of the air source heat pump or the ground source heat pump can be reduced to a certain extent, and the energy consumption is reduced.

And the third is that: in summer, when the upstairs area and the basement area need to be refrigerated, a bypass valve (not shown in the figure) is arranged in the water-loop heat pump 4, the bypass valve is opened, the water-loop heat pump 4 is closed, and the purpose of refrigerating the basement area and the upstairs area is achieved at the same time.

And fourthly: in winter, when the upstairs area and the basement area need to be heated, the built-in bypass valve of the water-loop heat pump is opened, the water-loop heat pump is closed, and the purpose of heating upstairs and downstairs is achieved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
