Abstract
The utility model provides a two-stage compressed-air heat pump water heater, including a first condenser, a first throttling element, a first evaporator and a first inverter compressor that connect to refrigerant tube in sequence to form a preliminary heating circuit and a second condenser, a second throttling element, a second evaporator and a second inverter compressor that connect to a hot water tube in sequence to form a secondary heating circuit. The second evaporator is arranged at the position where the heat released by high pressure refrigerant from the first condenser. The utility model is characterized by additional preliminary heating circuit, thereby, maintaining the temperature of working substance in secondary heating circuit and solving the problem of serious frosting and keeping thermal efficiency.
Description
Technical field
The utility model belongs to a kind of heat-pump hot-water unit, concretely, belongs to a kind of secondary compressed air heat pump water-heating machine group.
Background technology
" heat pump " this term is to use for reference " water pump " speech to get.In natural environment, it is moving that Water seeks its own level, and heat is to low potential temperature transmission.Water pump is pumped into the eminence utilization with water from lower.And heat pump can provide utilization to high potential temperature with low-temperature heat energy " pumping " (exchange is transmitted).Heat pump is identical with refrigeration machine in itself, just the operating condition difference.Its operation principle is, by electric energy drive compression machine, make working medium (as R22) shuttling movement that the physical phase transition process take place repeatedly, gasification heat absorption, the heat release of in condenser, liquefying in evaporimeter respectively, make heat constantly obtain exchange and transmit, and make unit realize heating (or refrigeration) function by the valve switching.In this process, the compressor of heat pump needs a certain amount of high-order electric energy to drive, what its evaporimeter absorbed is Lowlevel thermal energy, but the heat of heat pump output is available high level heat, quantitatively is the summation of its high level heat that consumes and absorb Lowlevel thermal energy.Heat pump has multiple, is called water resource heat pump with water as the heat pump of thermal source and heating medium.The water resource heat pump coefficient of performance (being the COP value) is higher than air source heat pump, and system performance is stable.
Teat pump boiler of the prior art adopts hot water as working medium, and by with the hot water pressurized gasification, its liquefaction release heat in addition again is with the hot water in the heating water tank.Yet this heat pump can only be operated in more than 0 degree Celsius, and is serious in the subzero frosting, the low and easy burn-out compressor of efficient; This makes it to use in that zone, China southeast is annual, northeastward, autumn, winter temperatures such as northwest, the west and south will be down to zero not enough half a year of service time in following area.
The utility model content
A purpose of the present utility model is to solve weak point of the prior art, and a kind of Teat pump boiler that can heat water under cryogenic conditions is provided.
For achieving the above object, secondary compressed air Teat pump boiler group of the present utility model comprises first condenser, first throttle element, first evaporimeter and first frequency-changeable compressor that is linked in sequence by refrigerant piping, form elementary heating circuit, with second condenser that is linked in sequence by the hot water pipe arrangement, second restricting element, second evaporimeter and second frequency-changeable compressor, form secondary heating circuit, described second evaporimeter is arranged in the position of the heat that sends after the high-pressure refrigerant liquefaction that can absorb first condenser.
Effect of the present utility model is, has increased elementary heating circuit, has guaranteed the temperature of working medium in the secondary heating circuit, thereby has solved the serious problem of frosting, has guaranteed the thermal efficiency.
Description of drawings
Fig. 1 is the schematic diagram of secondary compressed air Teat pump boiler group of the present utility model.
The specific embodiment
The utility model relates to a kind of secondary compressed air Teat pump boiler group, it is by heating the working medium (water) that is in the secondary heating circuit as working medium with cold-producing medium in elementary heating circuit, thereby working medium (water) temperature in the secondary heating circuit is raise, satisfy system and start requirement.Below in conjunction with accompanying drawing, feature of the present utility model is elaborated:
Fig. 1 is a principle schematic of the present utility model.With reference to Fig. 1, secondary compressed air Teat pump boiler group comprises first condenser 11, first throttle element 12, first evaporimeter 13 and first frequency-changeable compressor 14 that is linked in sequence by refrigerant piping, form elementary heating circuit 1, with second condenser 21, second restricting element 22, second evaporimeter 23 and second frequency-changeable compressor 24 that are linked in sequence by the hot water pipe arrangement, form secondary heating circuit 2, described second evaporimeter 23 is arranged in the position of the heat that sends after the high-pressure refrigerant liquefaction that can absorb first condenser 11.
Wherein, in elementary heating circuit 1, add cold-producing medium A, guarantee that cold-producing medium A gasification point is degree centigrade subzero, in first evaporimeter 13, cold-producing medium A absorbs the heat in the outside air, and warm gases at high pressure in being compressed in frequency-changeable compressor 14 enter heat release in first condenser 11 subsequently, cold-producing medium A is by 12 throttlings of first throttle element after the heat release, and the cryogenic gas cold-producing medium after the throttling enters first evaporimeter and absorbs heat again; Second evaporimeter 23 that first condenser, 11 liberated heats are adjacent and are wrapped in together in the heat-insulation layer absorbs, the heat that absorbs is in order to heat the water in second evaporimeter 23, the temperature that is the water of second evaporimeter rises to more than 20 degrees centigrade, thereby, water after heating can be used as working medium and be compressed into high temperature and high pressure gas through second frequency-changeable compressor 24 in secondary heating circuit B, heat release liquefaction in second condenser 21 is again got back to second evaporimeter 23 by second restricting element 22 after the heat release and is continued to absorb heat and the gasification that first condenser sends.The heat that second condenser sends is in order to the water in the heating water tank.
Only being preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should belong to technology category of the present invention.
