Description
Technical field
The present invention relates to a kind of air-conditioning system, specifically a kind of air-conditioning system with supplementary heat exchanger.
Background technology
1, existing air source heat pump system is in the impact easily by surrounding air environment, and when, environment temperature colder at weather is lower, its Energy Efficiency Ratio reduces greatly.And the stable operation that serious frost threatens system can be there is in long-play.Under cooling in summer operating mode, outdoor temperature makes up to 35 DEG C the condenser of off-premises station be in extremely hot heat exchange environment and bends down efficiency work in addition.
2, along with the progress of science and technology, researcher finds the i.e. solar energy-air source composite heat pump system that combined with air source heat pump system by solar energy, but the huge initial cost of this system is higher, and run complicated, fault is also many.
3, application number: CN201320892501.6 is called a kind of solar energy accumulation and air energy combined heat-pump system, and this system effectively can assist the operation of heat pump in winter but its shortcoming having amount of stored heat low is not suitable for longtime running, and accumulation of heat is not very stable.
4, application number: CN200810160419.8 is called balcony wall-hanging solar-air source composite heat pump system, this system vacuum tube accumulation of heat solves the low problem of efficiency of air source heat pump in winter, but can only solve winter problem and cannot process the problem of off-premises station heat transfer effect difference in summer.
Summary of the invention
Technical problem to be solved by this invention is the deficiency existed for above-mentioned prior art, and provides a kind of working environment improving condenser to improve family's used heat auxiliary type air source heat pump system of the operational efficiency of unit.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of family used heat auxiliary type air source heat pump system, comprise: air-conditioner outdoor unit and the indoor set be connected with off-premises station, it is characterized in that: also comprise a heat exchanger, this heat exchanger comprises water tank and is arranged on the heat exchange coil in water tank, described water tank is provided with water inlet and delivery port, and the two ends of described heat exchange coil are in parallel with the air-cooled coil pipe of described air-conditioner outdoor unit by three-way magnetic valve.
Described water tank is provided with temperature sensor.
In described water tank, be provided with overfall, the overflow pipe upper end arranged in water tank passes from described overfall.
Described water inlet is provided with stop valve.
Engineering process:
(1) winter condition: bath waste water and kitchen are discarded hot water through collecting by filtration in water tank by system, in the operation of heat pump of night air source when outside air temperature is very low, two three-way magnetic valves in parallel with off-premises station coil pipe are opened, close the ventilated disc tube passage flowing to off-premises station simultaneously, cold-producing medium after throttling will in water tank coil pipe evaporation endothermic, because wastewater temperature is apparently higher than outdoor environment, this will effectively improve the working environment of evaporimeter and significant operational efficiency and the heating capacity promoting heat pump, when temperature sensor finds that outdoor environment temperature significantly improves and when being better than water tank environment, the air-cooled coil pipe being initiatively switched to air-source side cuts out the heat exchange coil of water tank side by three-way magnetic valve, the operation of threat system of freezing in water tank, can set when water tank E Wendu is lower than 5 DEG C in a control program, initiatively be switched to the air-cooled coil pipe of air source.
(2) summer condition: the temperature of running water is probably 18 DEG C due to summer, far below the outdoor environment after noon, and the heat exchange property of water is far above air, so the temperature sensor when water tank inside finds that the temperature of water tank inside initiatively can be switched to water tank side heat exchange coil lower than during outdoor, make condenser condensation at a lower temperature, condensation effect can be improved significantly, the operation of optimization system thus improve the coefficient of refrigerating performance of unit.
(3) water tank adopts the mode water outlet of top water, and upper entering and lower leaving not only can effectively fully heat exchange but also can ensure that water tank is full of water all the time and security of system is run reliably.
Beneficial effect:
1, effectively utilize take a shower winter used heat and kitchen used heat to improve the operating condition of winter air source heat pump, can frosting be prevented, improve the heating effect of heat pump.
2, utilize the advantage of temperature lower than environment of running water in summer, improve the working environment of condenser, improve the refrigeration of air-conditioning.
3, attemperater top ability of swimming water outlet, makes water tank all be full of water all the time, can ensure the operation that system is always safe and reliable.
4, effectively make use of family's waste heat, while reducing the discharge of greenhouse gases, also respond the policy that national energy-saving reduces discharging.

Detailed description of the invention
By reference to the accompanying drawings, system is described:
A kind of family of the present invention used heat auxiliary type air source heat pump system, comprises air-conditioner outdoor unit 10, indoor apparatus of air conditioner 9 and for providing the water tank 6 of auxiliary heat-exchanging.In the entire system, water tank 6 is relation in parallel with the air-cooled coil pipe in off-premises station 10, and the mode that off-premises station 10 can select from the heat exchange coil air-cooled coil pipe or water tank works, and concrete connected mode is shown in Fig. 1.
1, the present invention mainly increases an auxiliary heat exchanger, by collecting bathroom or the domestic waste water of Various Seasonal, improve the operation conditions of air source heat pump, the hot water (35 DEG C) that normal big family can produce about 300L (+kitchen of taking a shower+wash clothes) in the winter time will improve heating effect greatly if allow evaporimeter place work under such circumstances, and summer running water temperature only have 18 DEG C, far below the environment temperature of outside, the working environment that can improve condenser greatly improves the operational efficiency of unit.
2, the composition of heat exchanger a: 0.3m
3attemperater, the copper heat exchange coil of one group of ring-type, two two-position three way magnetic valves, a stop valve and an overflow pipe.
Present system can lower energy consumption, improves the operating efficiency of heat pump machine:
1,0.3m
3the hot water of 35 DEG C institute can liberated heat Q when dropping to 5 DEG C
