The refrigeration machine that existing big-and-middle-sized central air conditioner system and middle-size and small-size business air conditioner system are adopted, often mainly be used as the summer air-conditioning cooling, a large amount of during this time condensation heat directly or by the indirect row of cooling tower to outdoor environment, there is the sub-fraction air-cooled heat pump unit to be used to heat in transition season, but the duration is very short usually, therefore utilization rate of equipment and installations is not high in 1 year, and expends a large amount of energy.As for water source heat pump system, though can realize stable heating winter in theory, but take all factors into consideration compressor, suction pump, suppress the good energy of water pump etc., the energy saving of its cooling, heating is to be worth discussion, and particularly it is to phreatic pollution with expend and be must to strengthen on the actual engineering sterilization research and monitoring.
Utilize the condensation heat that reclaims in the operation of heat pump much to be paid attention at present to produce this The Application of Technology of domestic hot-water, its basic principle is: adopt compressor refrigeration system to absorb heat from outdoor air, and running water is heated to temperature required with usefulness as the domestic hot-water by the fluorine water-to-water heat exchanger, applied fast in recent years, basic reason is: its power consumption only reaches below 1/4 of electric heater, annual energy consumption and integrated operation expense be far below electric heater, and be also much lower than gas heater, solar water heater.But be mainly used in the small-sized household Teat pump boiler of not being with air-conditioning cold and heat supply function at present, the air conditioner able to heat water that air-conditioning and domestic hot-water's function be integrated in one also do not occur now and be invested in market.
In big-and-middle-sized engineering and commercial occasion, mainly by in refrigeration system, increasing the heat that the one-level heat regenerator reclaims high-grade overheated zone in the conventional condenser, but its calorie value generally accounts for more than 10% of total condensation heat, and domestic hot-water's amount of producing is few, and energy-saving effect is limited.
When no matter domestic air conditioning or commercialization and engineering are produced the domestic hot-water with the heat pump in the air-conditioning, basically do not adopt the cycles, economized device, because the heating domestic hot-water needs condensation temperature very high to design temperature (generally getting about 50～60 ℃), cause pressure at expulsion very high, compression ratio is excessive, particularly even more serious under the condition in the winter time, this causes Energy Efficiency Ratio EER (heating capacity/input power) to reduce greatly on the one hand and power consumption is increased, economy worsens, the fault rate of parts such as compressor increases on the other hand, and the life-span reduces.
Generally produce boiling water and often adopt electrothermal, combustion gas etc., the former directly expends the high-grade electric energy in a large number, the latter has also expended the high-grade primary energy, and the heat energy conversion ratio of general domestic gas cover has only about 20～30% the therefore in fact also very high energy waste of existence.
Emerging in the market small-sized household heat pump techniques is produced the product of boiling water, system adopt greatly improve pressure at expulsion with obtain surpass 100 ℃ delivery temperature with the boiling water of purchasing, the compression ratio of heat pump cycle is excessive, cause Energy Efficiency Ratio greatly to descend, badly influence compressor and complete machine service life, and heat exchanger area is excessive, makes investment of equipment, running cost all comparatively high, be difficult to obtain the expection energy-saving effect, thus in fact far be not can practical application matured product.
Because heat pump or air conditioner and water heater segmentation heat-obtaining are most important, each section heat exchange characteristic has nothing in common with each other, the heat exchanger structure of selecting respectively to be suitable for is the key that guarantees high-performance, high reliability, but adopt same heat exchanger to extract condensation heat in the present product usually, exchange capability of heat to overheated zone and mistake cold-zone is very poor, can not realize classification heat-obtaining targetedly well, cause heat exchange area excessive, thermal property is relatively poor, can't satisfy basically whole condensation heat are all taken out the needs of producing the domestic hot-water.Simultaneously, existing equipment can't accomplish that also the hot water of producing the higher temperature level is used for accumulation of heat when producing the domestic hot-water of proper temperature, needs with the operating peak regulation of realization system.
