Description
Technical field:
The present invention relates to Teat pump boiler technical field.
Background technology:
Teat pump boiler is a kind of compression by cold-producing medium, condensation heat, throttling expansion, evaporation endothermic, make the heat energy absorbing the air energy that absorbs from environment or water, be promoted to the heat energy that temperature is higher, domestic hot-water supply or confession heating installation, have obvious energy-saving effect, the Energy Efficiency Ratio of general Teat pump boiler is 3～4.Wind-water double-source heat pump is a kind of energy-saving heating equipment that can absorb wind regime and water source heat energy, has advantages of widely applicablely, is widely used in the occasions such as publilc baths, swimming pool, hotel; Multifunctional heat pump has heat supply, refrigeration, and water heating function, energy-saving effect is better.The applicant has applied for multinomial relevant patent.For example, simple high efficient and reliable cooling/warming conditionner and hot water device (201010215579.5, 201020245130.9), the open-and-shut double heat source heat pump hot water apparatus of a kind of refrigerating circuit (200910181300.3), help each other Defrost method and the five circulation double heat source heat pump water heaters (201010211846.1) of air source hot pump water heater, air source hot pump water heater and the five circulation double heat source heat pump water heaters (201020240385.6) of helping each other and defrosting, parallel mutual defrosting air source heat pump water heater (201010272024.4, 201020516806.3), the compact cold-heat air-conditioning, water-heating three-purpose machine (201010568937.0 of self-built Natural Circulation stream heat exchange, 201020637139.9), energy-conservation cold-heat air-conditioning, water-heating three-purpose machine (02116049.X of a kind of four seasons, 02220342.7) etc., two source multifunctional heat pumps (201110202512.2, 201120255655.5) due to applied for patented technology for problem different, or solve the same problem incomplete same scheme, so constantly apply for again new patent.
The double-source heat pump hot water machine of existing two classes, a class is the structure of utilizing wind-cooled cold-water unit to add a recuperation of heat hot-water heater between exhaust outlet of compressor and cross valve air inlet.The double-source heat pump hot water machine publicizing on this market, its major function is that the summer provides the cold water of idle call, recovery section heat of condensation water heating, the winter, for more than 40 hot water heatings of spending, is difficult to provide 55 ℃ or above domestic hot-water; Because when utilizing water source heat exchanger heat absorption or refrigeration, can not reclaim the condensation heat water heating of whole cold-producing mediums, because refrigerant gas all condenses into liquid in hot water heat exchanger, then enter wind regime heat exchanger, system can show short of refrigerant, hydraulic performance decline; In the winter time, to wind regime heat exchanger defrosting, must rely on water source has water, if water source is anhydrous, just cannot absorbs heat wind regime heat exchanger is defrosted, and water in water source heat exchanger also cannot be antifreeze; This double-source heat pump hot water machine can not be used in spent hot water's recovery waste heat of the limited similar bathing occasion in water source.Wind/water double-source heat pump hot water integrated machine of another kind of multiple heat absorption pattern, take and provide domestic hot-water as object, its design be wind regime heat exchanger and water source heat exchanger all as evaporimeter, and a hot water heat exchanger condenser uses, advantage is to utilize wind regime and water source complementation to carry out water heating; But shortcoming is, in the winter time, its wind regime heat exchanger can frosting, needs defrosting, in addition, the water of its water source heat exchanger water side path, damage equipment in the winter time also can freeze; And take, provide the design of hot water as wind/water double-source heat pump hot water integrated machine of main existing multiple heat absorption pattern, cannot be to water source heat exchanger heating and anti-freezing, this is steady criminal of the serious safety of wind/water double-source heat pump hot water integrated machine of multiple heat absorption pattern; Moreover, by the performance of the water condenser of standard condition design, in summer and winter, all reducing, heat absorption capacity is poor in the winter time for wind regime, water source heat exchanger, makes Teat pump boiler when high temperature and the operation of low temperature condition, and performance is all bad.

Innovative point of the present invention mainly contains:
The feature of the double heat source heat pump hot water integrated machine that 1, the present invention is switched with two cross valves is to use two cross valves, and three kinds of cyclic switchings that complete double heat source heat pump hot water integrated machine are controlled, and structure is relatively simple, but function ratio is more complete; All arrange the independent source work stressing, and be equipped with two thermals source or series connection, or parallel operation, to exert oneself large, Energy Efficiency Ratio is high.
Three kinds of discrete circulating refrigerant circuit systems of five check valves of two cross valves of technical scheme I, its second cross valve be arranged in flow controller before, the second cross valve is that cold-producing medium hot high pressure fluid is switched, the conductive heat loss of the high-temperature control gas of solenoid pilot valve that can reduce cross valve to cross valve; This design, at fill order's wind source heat pump circulation time, water source heat exchanger is just as subcooler, without worrying whether water source heat exchanger has water, problem whether can be icing; And cold-producing medium is to move, can not produce cold-producing medium overstocked problem in certain heat exchanger in a series loop; When carrying out water source+wind regime parallel circulating pattern, to compare with water source+wind regime series connection connection circulation pattern, evaporimeter flow resistance is little, can increase more heating capacity, has higher COP.Do not worry the leakage of five check valves, if there is leakage, be also equivalent to the throttling that resistance in parallel is very large, leak fluid also enters evaporimeter.Its defrost cycle, if there is water at water source, can absorb heat from water source, reduces and absorbs heat from hot water.
