A kind of domestic heat pump water heater with heat reclamation device
Technical field
The utility model relates to a kind of domestic heat pump water heater with heat reclamation device.
Background technology
Along with development and national economy and growth in the living standard, air-conditioning has become the important technical that people build indoor environment.By the end of the year 2008, the every one hundred houses air-conditioner of National urban resident owning amount has on average reached 61.8, and wherein Beijing is 119.31, and Shanghai is 135.80, and Chongqing is 156.67.A statistics according to 2008 shows that Shenzhen's air conditioning electricity load in recent years accounts for 60% of peak of power consumption load in summer.Air-conditioning will be to a large amount of condensation heat of environmental emission when cooling condition moves, and its value is up to 1.3 times of refrigerating capacity.A large amount of uses of domestic air conditioning make a large amount of condensation heat directly enter atmosphere, cause bigger energy waste.The heat that distributes makes ambient temperature raise again, causes the serious environmental thermal pollution, makes " tropical island effect " the further aggravation in city.And a large amount of dischargings of condensation heat raise the condenser ambient temperature, are unfavorable for the condenser heat radiation, cause condensation temperature to raise, and the operation energy consumption of air-conditioning unit raises.Heat recovery technology not only can improve energy utilization rate, and can reduce the influence of air-conditioning system to surrounding environment.Therefore, advocate the period of energy-saving and emission-reduction, take heat recovery technology, become an extremely urgent job at current this.
Air-conditioning recuperation of heat utilization technology both can save energy, and can reduce again the thermal pollution of environment and was more and more paid attention to by domestic experts and scholars.But for the research of air-conditioning system recuperation of heat, is the research that the recuperation of heat of large-scale central air conditioner systems such as factory, hotel is carried out mostly at present both at home and abroad, and few to the research of the split type domestic air-conditioning system of mini zone recuperation of heat.
Traditional split type domestic air conditioning commonly used not only can't satisfy the needs of user to refrigeration, heating and heat supply water, and can't realize the recycling to condensation heat, makes these useful heat waste.The split type domestic heat pump air conditioner of present band recuperation of heat is that outer machine, press-bearing water tank and the interior machine of split type family expenses are formed, though can realize recuperation of heat, can when interior mechanism is cold, produce the domestic hot-water, has following problem:
1, because the split type domestic heat pump air conditioner of existing band recuperation of heat is outer machine, press-bearing water tank and the interior machine composition of split type family expenses; Can only satisfy the demand of producing a domestic hot-water and a cold space of usefulness; Can't satisfy the demand in the cold space of a plurality of usefulness of family expenses, promptly a cover system can't satisfy domestic hot-water, the refrigeration of whole family expenses dwelling house, the demand of heating.
2, interior machine can't realize that for walking the refrigerant design more comfortable floor heating mode heats.

The technical scheme that the utility model adopts is: the domestic heat pump water heater of band heat reclamation device; Comprise the compressor, cross valve, air-cooled condenser, electric expansion valve, the heat exchanger that connect successively; Said heat exchanger is arranged on indoor; Second valve port of said cross valve connects heat exchanger, and the 3rd valve port of said cross valve connects air-cooled condenser, and the 4th valve port of said cross valve connects the return-air mouth of compressor; Also comprise press-bearing water tank, reversal valve; The inlet of said reversal valve connects the exhaust outlet of compressor, and first outlet of said reversal valve connects first valve port of cross valve, and said press-bearing water tank is connected between first valve port of first outlet and cross valve of reversal valve.
Said indoor heat exchanger is a water cooling heat exchanger; On the heat exchanging water pipe of indoor heat exchanger, connect water circulation system; Connect to form by indoor heat exchanger, water pump, fan coil heat exchange device, floor heating coil pipe, expansion tank, electromagnetism threeway, insert the porch that is connected that is located at fan coil heat exchange device and floor heating coil pipe by water pump, indoor heat exchanger, said electromagnetism threeway after said fan coil heat exchange device and the parallel connection of floor heating coil pipe.
Said expansion tank is arranged on the entrance side of electromagnetism threeway.
On said fan coil heat exchange device, the fan coil blower fan is set.
Blower fan outside on said air-cooled condenser, being provided with.
The beneficial effect of the utility model is:
1) cover system satisfies domestic hot-water, the refrigeration of whole family expenses dwelling house, the demand of heating.Can realize that more comfortable floor heating mode heats.
2) adopt reversal valve and cross valve to switch refrigerant and flow to, realize various modes (wind dish refrigeration, floor heating, system domestic hot-water, wind dish chilled water+domestic hot-water, floor heating+domestic hot-water), system is simple and reliable, and control easily.
3) system has three heat exchangers; When in interior machine wind dish refrigeration and when producing the domestic hot-water simultaneously, three heat exchangers are to be connected in the refrigerating circuit, when water tank temperature when set water temperature or environment temperature are very high; System loading is very big; Can guarantee system's reliability service through regulating outer blower fan output, practice thrift operating cost to reduce system's operating pressure and power consumption.
