Description
The present invention relates to a kind of heat pump air conditioner and water heater, belong to system control method and system and form, particularly a kind of water-heater system of energy-conservation, varying duty.
Technical background
Teat pump boiler is a contrary Carnot cycle principle of utilizing heat pump, and the temperature difference heat absorption by cold-producing medium and outside air, the compression of compressor heat and the processes such as lasting heat exchange of cold-producing medium and water, and water is heated.Compare with conventional water heaters, it has the following advantage Teat pump boiler: the security of Teat pump boiler: conventional water heaters is with combustion gas, electricity and solar energy are main, three minutes all over the world, the gas heater security is relatively poor, insufficient and the hydraulic pressure instability of burning easily causes combustion gas poisoning and scald incident, the electric leakage hidden danger and the dwelling house imperfect earth of electric heater also cause serious threat to consumer's life security, the characteristics of solar water heater water-storage formula have determined it when fine day, water temperature may be very high, cause scald, the auxiliary heating of overcast and rainy electricity but stays potential safety hazard, different with above water heater, the Teat pump boiler process of heating is to add water in the hot-water cylinder by the high-temperature high-pressure refrigerant gas that compressor is discharged, electricity is mainly used in compressor, gas after heating is by the coil pipe of outer disc type and the water heat-shift in the enamel water pot, water power separates fully, like this, neither there is electric leakage hidden danger, saved anti-creeping worry, also avoided electric heating tube surface temperature height, easily fouling and influence the drawback of the efficiency of heating surface is really accomplished to be perfectly safe.Teat pump boiler energy-conservation: owing to adopt heat pump techniques, can be with a large amount of low-grade thermals source (airborne heat) by compressor and cold-producing medium, change high-grade available heat energy into, Teat pump boiler is owing to absorbed a large amount of airborne heats, Energy Efficiency Ratio is more than 3, be the every consumption kilowatt-hour of compressor of Teat pump boiler, can produce electrical heating and consume the hot water that 3 degree electricity produce, saved the energy greatly.With 120 liters of Teat pump boilers is example, compressor horsepower is 500 watts, thermal efficiency value is 370% (the standard condition environment temperature is 20 ℃), is about four times (the electric heater thermal efficiency is 95%) of common electrical water heater, has saved electric energy greatly, same 120 premium on currency are raised to 55 ℃ from 15 ℃, the common electrical water heater needs 6Kw, and Teat pump boiler only needs 1.5Kw, has not only saved expense, large tracts of land is promoted also can relax the power tense situation greatly, has very big realistic meaning
Yet Teat pump boiler realizes truly having very big difficulty technically, this is because family all needs hot water throughout the year, and the condensation side water temperature often will be raised to 55 ℃ from 5 ℃, this design and running to heat pump has brought great difficulty, and conventional heat pump air conditioner is difficult to adapt to so wide excursion.In patent 200310121162.2 indoor air source heat pump water heaters, evaporimeter being installed in indoor, having alleviated the pressure of regulating to a certain extent, obviously is unpractical but compressor is placed in indoor, and the noise of compressor is that the user is difficult to bear.In addition, domestic Teat pump boiler all is to adopt invariable frequency compressor and heating power expansion valve or capillary-compensated, and this obviously can not satisfy above-mentioned requirements.
The present invention is exactly that capacity-variable air conditioner system and methods such as electric expansion valve, bypass adjusting are carried out system control, and a kind of more stable, energy-conservation, Teat pump boiler that accommodation is wide is provided, and makes that control is simple, is easy to industrialization promotion.
Summary of the invention
The purpose of this invention is to provide that a kind of gamut can be regulated, energy-conservation Teat pump boiler.
Technical scheme of the present invention is: system comprises variable conpacitance compressor system (1), outdoor heat exchanger (2), outdoor fan (3), bypass solenoid valve (4), cross valve (5), vapour liquid separator (6), electric expansion valve (7), delivery temperature probe (8), environment temperature probe (9), outer dish temp probe (10), suction temperature probe (11), outdoor controller (12), indoor control panel (13), control panel (14), indoor heat exchanger (15), heat preservation storage water tank (16), leaving water temperature probe (17), inner disc temp probe (18) is with corresponding refrigerant pipe and connection.Indoor control panel sends to outdoor controller to hot water temperature's demand and leaving water temperature, the inner disc temperature that the user sets at indoor control panel, outdoor controller is opened compressor load according to the data and the outdoor environment temperature of indoor controller, and pop one's head in electronic expansion valve regulation cold medium flux according to outer dish temp probe, suction temperature, from outdoor environment, obtain heat by outdoor fan.
Fig. 1 is a system diagram;
1 variable conpacitance compressor system; 2 outdoor heat exchangers; 3 outdoor fans; 4 bypass solenoid valves; 5 cross valves; 6 vapour liquid separators; 7 electric expansion valves; 8 delivery temperatures probe; 9 environment temperatures probe; 10 outer dish temp probes; 11 suction temperatures, 12 outdoor controllers of popping one's head in; 13 indoor control panels; 14 control panels; 15 indoor heat exchangers; 16 heat preservation storage water tank; 17 leaving water temperatures probe; 18 inner disc temp probes; 19 outlet pipes; 20 water inlet pipes
Specific embodiment
Wherein, for the consideration of cost, variable conpacitance compressor system (1) can adopt double-compressor, and the present invention adopts the compressor parallel of a 2HP and a 1HP.With the leaving water temperature is target, different according to outdoor temperature and water temperature, provide stable leaving water temperature: 2HP+1HP, 2HP+1HP+ bypass, 2HP, 2HP+ bypass, 1HP, 1HP+ bypass by regulating following six energy ranks, and the energy-conservation stable operation by the temperature difference control method within the specific limits between outer dish temp probe (10), the suction temperature probe (11) is kept system.
For example: when outdoor temperature is 20 ℃, this be the user to set leaving water temperature be 42 ℃, and 10 ℃ of initial water temperatures, compressor primary power rank is decided to be 2HP; When water temperature was raised to 35 ℃, the energy rank was decided to be the 2HP+ bypass; When water temperature was raised to 39 ℃, the energy rank was decided to be 1HP, and when water temperature was raised to 42 ℃, the energy rank was decided to be the 1HP+ bypass, and when water temperature was raised to 44 ℃, the energy rank was decided to be 0, i.e. close compressor; When water temperature dropped to 42 ℃, the energy rank was decided to be the 1HP+ bypass.So analogize, the energy rank of compressor is along with the difference variation of design temperature and actual leaving water temperature.
Electric expansion valve is according to corresponding adjusting of the temperature difference between outer dish temp probe (10), the suction temperature probe (11) simultaneously.
When on the outdoor heat exchanger during frosting, electric expansion valve is regulated as stated above, makes that the outdoor heat exchanger bulk temperature is even, prolongs the frosting time greatly.
