Description
Technical field
The present invention relates to a kind of air source hot pump water heater, refer in particular to a kind of air source heat pump water heater swimming pool constant temperature system.
Technical background
The traditional hot water water supply scheme of China's swimming pool mainly is to adopt the Teat pump boiler direct-heating type at present, and after water temperature in the swimming pool reduced, water charging system covered tap water the heat storing and heat preserving water tank again, after the main frame heating, injects swimming pool.Water temperature raise after hot water and swimming-pool water mixed, and swimming pool is because the injection of a large amount of hot water causes the pool inner water amount to increase, exceed swimming pool institute water requirement, have to again water unnecessary in the pond is drained, circulation and so forth, the water temperature in swimming pool reaches design temperature.Because the tap water water temperature is well below swimming-pool water, this will directly cause adding hot tap-water than the heating swimming pool water consumption of manying more power, and a large amount of electric energy are wasted; And because the injection of a large amount of hot water, the swimming pool water level constantly raises, and for mixed water temperature being reached design temperature, has to again a big chunk mixing water is emitted, and has greatly wasted water resource so again.In recent years, " severe power shortage " generally broken out in all parts of the country, northern China some areas even adhesion occurred and apply flexibly water and all be difficult to ensure.The seriousness of " severe power shortage " and " water shortage " problem has profoundly been told us, and energy conservation is very urgent.Therefore, traditional swimming pool hot water water supply scheme can not satisfy demands of social development, must have a kind of more energy-conservation system to replace.
Summary of the invention
Content of the present invention is the defective at the prior art existence, and existing swimming pool water supply scheme is improved, and a kind of energy saving and environment friendly swimming pool constant temperature system is provided.
In order to realize such purpose, the invention has designed a kind of energy saving and environment friendly swimming pool constant temperature system.This system comprises the main frame that contains refrigeration system, the heat storing and heat preserving water tank, hot water circulating pipeline, the backwater heating pipe line, swimming pool and controller, the swimming pool temperature pick up places in the swimming pool, controller is to heat storing and heat preserving water tank and swimming pool middle water level and temperature is gathered and real-time judge, the control circulating water pump, ball valve, the operation of electromagnetic valve and main frame, hot water circulating pipeline top is connected main frame by first ball valve with the heat storing and heat preserving water tank, hot water circulating pipeline top between first ball valve and the main frame also connects target stream switch, the hot water circulating pipeline lower part is by first circulating water pump, first water filter, the soft water treatment system is connected main frame with second ball valve with the heat storing and heat preserving water tank, the heat storing and heat preserving water tank adopts nonbearing structure, built-in water returning disk heat exchange of heat pipe, the water tank temperature sensor, high water level switch and low-water level switch are contained in heat storing and heat preserving water tank upper and bottom respectively, backwater heating pipe line top is connected the water returning disk heat exchange of heat pipe by second circulating water pump with swimming pool, backwater heating pipe line lower part is connected the water returning disk heat exchange of heat pipe with sewage disposal system by second water filter with swimming pool, form closed backwater heating pipe line, heat storing and heat preserving water tank bottom is connected with swimming pool with the 3rd circulating water pump by entering water electromagnetic valve, connects running water pipe by the moisturizing electromagnetic valve above the heat storing and heat preserving water tank.
The height of high water level switch and low-water level switch control water tank middle water level, water temperature in the water tank temperature sensor sensing heat storing and heat preserving water tank.Hot water circulating pipeline makes main frame cold-producing medium and water carry out interchange of heat.Adopt external first circulating water pump that the circulation power of hot water circulating pipeline is provided.This system has utilized swimming pool and heat storing and heat preserving water tank water temperature to exist than big-difference dexterously, utilize second circulating water pump to make recirculated water in the water returning disk heat exchange of heat pipe, carry out interchange of heat, need not the frequent starting main frame just can heat swimming-pool water, can also keep water temperature constant, construction costs is low.When swimming-pool water is heated, can also purify Chi Shui by sewage disposal system, remove impurity in the water by second water filter, make that swimming-pool water cleans all the time, health.It is a kind of round-the-clock swimming pool constant temperature system applied widely, advantage such as reliability is high, energy-conservation, health that has.Adopt controller that system is controlled automatically, make system's operation need not be manually on duty and operate in optimum state all the time, both kept the water temperature of swimming pool, reduce the power consumption of unit again, also saved a large amount of waters.
In the time of first water supply, start the moisturizing electromagnetic valve earlier the heat storing and heat preserving water tank is mended cold water, when water level arrives low-water level switch, first circulating water pump starts, after the operation some minutes target stream switch is detected, closed as target stream switch, then start main frame water in the heat storing and heat preserving water tank is heated.Be heated to design temperature, then the 3rd circulating water pump starts, hot water is extracted in the swimming pool, and then the moisturizing heating, reach the setting requirement up to water temperature, water level.In the process of using, because constantly the scattering and disappearing of heat, and cause water temperature constantly to reduce, when the water temperature of swimming pool is reduced to design temperature when following, second circulating water pump starts takes out swimming-pool water to the heat storing and heat preserving water tank.The hot water that swimming-pool water enters in water returning disk heat exchange of heat pipe and the heat storing and heat preserving water tank behind sewage disposal system purification, the second water filter removal of contamination carries out interchange of heat, and temperature flows back to swimming pool after raising again, and is continuous and so forth, makes swimming-pool water keep constant temperature.
This system adopts external circulating water pump (second circulating water pump and the 3rd circulating water pump) that the circulation power of hot-water return is provided; Heating water tank adopts built-in water returning disk heat exchange of heat pipe nonbearing structure, inlet pipeline is connected with the tap water pipe network, and the attemperater upper and lower part is provided with the circulating hot water pipe respectively, built-in backwater coil pipe, and be connected with circulating water pump, thereby form closed hot water circulation loop with main frame.This system utilizes the set water temperature of swimming pool and Teat pump boiler attemperater to have the big temperature difference dexterously, utilize circulating water pump that the water in the swimming pool is drawn back and filtered, in heating water tank, carry out interchange of heat through coil heat exchanger with high temperature water, reach design temperature after circulating water pump quit work.Water in the swimming pool is through water treatment facilities, and the heating that circulates again and again not only can keep water cleaning constantly, can also make the water in the swimming pool remain on needed temperature.The water of heating water tank can be not contaminated, still can be used as the domestic hot-water and use.
