Description
Technical field: the utility model belongs to air-conditioning technical field, relates to a kind of associating aircondition that fully utilizes solar energy, geothermal energy.
Background technology: current society, for providing refrigeration, heating and domestic hot-water's the energy, various buildings mainly still rely on coal and oil after all, worsening shortages along with these energy, and their environmental pollutions in combustion process, people are strengthening such as solar energy, these renewable development and use of not having the new forms of energy of any environmental pollution again of geothermal energy.At present, prior art can utilize solar water heater to be building heating and domestic hot-water supply, utilize the geothermal energy unit to be architecture refrigerating, heating and domestic hot-water supply, but, they all are the technology of using separately, and all have defective: the extraction such as geothermal energy must expend a large amount of electric energy, and solar energy is at the cloudy day with just can't extract night, therefore, their range of application and level of application all are very limited.Recently, also the someone attempts solar energy and geothermal energy in conjunction with utilization, for example Chinese patent CN2394139Y, CN2391123Y, CN2400729Y disclosed " solar energy, underground heat hot and cold water unit " are several examples wherein, but these several technology are similar, they all are on the structure solar heat pump circulatory system and ground to be improved by circulation system internally, and the mixing stack by these two kinds of thermals source fully utilizes then.This improved greatest drawback is exactly a complex structure, is not easy to apply.
Summary of the invention:
The purpose of this utility model is: at the prior art defective, a kind of central air conditioning plant that fully utilizes solar energy, geothermal energy is provided, it is under the prerequisite that does not change internal structure, by utilizing the existing equipment of solar energy and geothermal energy, common heating, refrigeration and the domestic hot-water supply problem that solves modern architecture, it can fully improve solar energy utilization rate, can effectively reduce the power consumption in the geothermal energy utilization process again.
Technical solution of the present utility model is:
A kind of solar energy, geothermal energy associating central air conditioning plant, comprise geothermal energy unit, solar water heater, it is characterized in that geothermal energy B of Unit SD is connected with the heat/cool penstock by the heat/cool water pump by the heat/cool water pipe with solar water heater BST, wherein, geothermal energy B of Unit SD places the front portion of heat/cool water pump, the intake pipe of this unit leads to water intake well by geothermal source valve and geothermal source pump, and return pipe leads to back water well; Solar water heater BST places the rear portion of heat/cool penstock, and the outlet pipe of this water heater leads to user YH by the straight-through water supply valve of solar energy: the return pipe of user YH links to each other with geothermal energy B of Unit SD by valve; In addition, the heat/cool water pipe is the second heat/cool penstock direct user YH by connecting behind the heat/cool penstock, the outlet pipe of solar water heater BST connects user's water storage tank SX by solar water supply valve, solar water pump and heat exchanger, again through valve direct user YH; The all controlled device K control of aforesaid all valves, pump and geothermal energy B of Unit SD.
Aforesaid solar energy, geothermal energy associating aircondition is characterized in that being serially connected with solar water heater on the water intaking pipeline of geothermal energy unit, in order to improve the underground water temperature, make geothermal energy unit usefulness higher.
The utility model combines solar water heater and geothermal energy unit, and its outstanding advantage is exactly environmental protection, energy-conservation, and the former is that the latter makes so because of its structure because they self all are the green energy resource causes.Because use solar water heater can not solve round-the-clock heating and domestic hot-water's problem separately, can not solve the refrigeration problem; Though and rely on the geothermal energy unit can realize the heating of whole building, refrigeration and domestic hot-water's problem separately, it must consume a large amount of electric energy, its operating cost costliness.Give full play to and adopt the utility model that the two advantage was separately got, and shortcoming is separately remedied mutually.Undoubtedly, use solar energy than use geothermal energy economy many, the two is combined, finish under the prerequisite of same task, the time of geothermal energy unit work then significantly reduces, power consumption also can greatly reduce.This shows and use the utility model to receive simultaneously to make full use of solar energy, utilize geothermal energy that saves energy to greatest extent there is no the technique effect of any environmental pollution with the power consumption of minimum.Compared with prior art, because it need not to change the internal structure of existing equipment, and just by setting up a kind of new annexation and controlling the problem of complex utilization that solves two kinds of energy, therefore, it also has simple in structure, saves operating cost and advantage easy to utilize
