Abstract

Disclosed is a well type air-conditioner, which is composed of an air-conditioning unit and an underground heat exchanger. Compared with the present air-cooled air-conditioner, the utility model is characterized mostly in that an external heat exchanger of the air-cooled air-conditioner is replaced by an underground heat exchanger. Thus, the utility model has the advantages that the running of the air-conditioning unit is not influenced by the environment temperature; the heat exchanger does not contact with the air and does not need to be defrosted; the underground water is used as the cold and hot source, so the effective power is increased obviously. According to estimation, the power can saved about 40 percent. The utility model is in simple structure and reasonable design.

Description

And formula air conditioner

The utility model belongs to the design and the manufacturing technology field of air conditioner.

The air-cooled air conditioner of Xiao Shouing is made up of indoor and outdoors two parts in the market.All be cold-producing medium with freon, carry out cooling and warming as cold and heat source, because the physical property of cold-producing medium and the reasons in structure of air-cooled air conditioner in use just expose many weak points with surrounding air.1, in the winter time at the bottom of the ambient air temperature in the time of-15 ℃, the air-cooled air conditioner machine just can not normally start, and promptly enables to start, heating effect is also poor especially.2, environment temperature needs power consumption repeatedly to defrost to external heat exchanger, otherwise can influence heating effect in the time of 2 ℃～-7 ℃.If 3 ambient air temperatures are higher than+35 ℃ the time, the refrigerating capacity of air-cooled air conditioner machine will descend, or cause shutdown because of the air conditioner hypertonia.When 4, needing to heat in the winter time, the air-cooled air conditioner machine but descends because of environment temperature, and effective power also descends, and can not reach the purpose that heats heating.When freezing summer, because of the environment temperature height, influence the condensation of cold-producing medium, cause power consumption big, effective power is low, and refrigerating capacity descends.

It is the well formula air conditioner of exchange media with water that the purpose of this utility model provides a kind of, to solve the drawback that existing product exists.

The utility model is achieved by following technical solution.Its structure is as shown in drawings: be made up of room conditioning unit and ground heat exchanger, have blower fan (2) in air conditioner housing (1).A compressor (4) is arranged at the bottom in body.On compressor, connect a four-way change-over valve (5).On reversal valve, connect indoor heat exchanger (3).On another valve port of four-way change-over valve, have ground heat exchanger (7).Have thermal insulation casing (8) on one side pipe of ground heat exchanger.Between ground heat exchanger and heat exchanger, have capillary (6).Operation principle of the present utility model is: during refrigeration, refrigerant flow direction is compressor-four-way change-over valve-ground heat exchanger-capillary-indoor heat exchanger-four-way change-over valve-compressor.When heating, refrigerant flow direction is compressor-four-way change-over valve-indoor heat exchanger-capillary-ground heat exchanger-four-way change-over valve-compressor.The refrigeration of air conditioner, heat and effective power closely related with the evaporating temperature of cold-producing medium with condensation temperature.Evaporating temperature is high more, and condensation temperature is low more, and refrigerating capacity and heating capacity are just high more.Well formula air conditioner be with underground water as cold and heat source, freeze and heat, can effectively improve the evaporating temperature and the condensation temperature of cold-producing medium, make well formula air-conditioner refrigeration, heat with effective power and be significantly improved.Because the thermal capacity of water is big, and conduction cooling, good in thermal property, so water is best low-temperature receiver and thermal source, the especially underground water of air conditioner.Through verification, phreatic water temperature is identical with local annual environment mean temperature, and only high sometimes 1～2 ℃, this temperature is very stable, thus both can be as the low-temperature receiver of summer refrigeration, also can be as the thermal source of winter heating.Well formula air-conditioner is to be the water source with the phreatic water, and the place of phreatic water is arranged in every underground 10～60 meters scopes, all can use this air conditioner.And do not need water lift equipment, do not consume underground water, not polluted underground water.Its installation method is identical with existing product, just beats nearby-the eye well, and the degree of depth of well is not descended well casing with till being deep into the water-bearing layer.Copper pipe is curved the U font, and two tube pitch are 5～10 centimetres, copper pipe are inserted underground, as the ground heat exchanger of well formula air conditioner, the surface of a copper pipe puts insulating tube therein, begin downward 8～10 meters from ground, carry out exchange heat in advance to prevent two pipes.

The utility model is simple in structure, and is reasonable in design.Compare with existing air-cooled air conditioner machine, maximum characteristics are the external heat exchangers that replaced the air-cooled air conditioner machine with underground heat exchanger.The advantage of doing like this is, unit work is not subjected to the influence of environment temperature, and heat exchanger is ingress of air not, just do not need defrosting.Adopt underground water as cold and heat source, effective power is improved significantly.According to measuring and calculating, saving electric energy can reach about 40%.

The utility model playback system is identical with existing product basically.Compressor wherein, four-way change-over valve, indoor heat exchanger etc. are standard or universal component, can reproduce by the known technology manufacturing of making the air-conditioning unit with reference to this specification and accompanying drawing.

Claims

Well formula air conditioner is characterized in that a compressor (4) is arranged at the bottom in the body, has ground heat exchanger (7) on another valve port of four-way change-over valve (5), has thermal insulation casing (8) on the side pipe of ground heat exchanger.
