The mode of operation of the utility model
1, refrigeration and heat recovery mode
The high temperature and high pressure gaseous refrigerant of compressor outlet at first gets into first order heat regenerator, and the release portion condensation heat is owing to be in exhaust outlet of compressor; The temperature of cold-producing medium is high; Therefore, first order heat regenerator can obtain the great amount of high-temperature condensation heat, can produce the hot water of higher temperatures.Get into second level heat regenerator again, can produce the hot water lower slightly than first order temperature, cold-producing medium further is cooled; A mouth from four-way change-over valve gets into then; The b mouth flows out, and gets into condenser again, is born the discharging of remaining condensation heat by condenser; This moment is according to the platform number of condensing pressure startup blower fan, to reach the degree of supercooling of design demand.After high pressure liquid refrigerant comes out to get into the expansion valve throttling expansion by condenser 5, get into evaporimeter 7 vaporization of absorbing heat, until overheated, get into the cross valve reversal valve afterwards, got into by the c mouth, the d mouth flows out, and returns compressor at last, the completion kind of refrigeration cycle.
When the hot-water heating system of first and second grade heat regenerator does not need heat, this two levels of thermal recover only is equivalent to the part of compressor air-discharging pipeline section, gets into air-cooled condenser afterwards, discharges whole heats, and this situation has only realized independent cooling, and efficient is minimum.
When first and second grade heat regenerator and outdoor air-cooled condenser all have heat exchange simultaneously, just realized refrigeration and heated the situation of carrying out simultaneously.The hot-water heating system of two levels of thermal recover can freely be obtained heat according to the variation to heat demand, has promptly realized freely reclaiming of heat.The heat of heat regenerator discharging is big more, and the efficient of system is high more.
When net quantity of heat is all taken away by the hot-water heating system of first and second grade heat regenerator, when cold-producing medium has been emitted whole condensation heat, even to cross when cold and hot, this situation has realized superthermal recovery, the efficient of system reaches the highest.
Refrigeration is carried out with recuperation of heat simultaneously, guarantees normal cooling condition, realizes that according to the demand of heat recovery system superthermal recovery, portion of hot reclaim and three kinds of situations of no recuperation of heat, need not to regulate any valve.
The characteristics of summer mode:
(1) every grade of heat regenerator reclaim heat what can set the demand of heat by hot-water heating system separately, need not operate any valve, obtain the heat freedom and flexibility.The ratio of the heat that reclaims and total condensation heat can freely be obtained in 0 ~ 100% scope.
(2) the two levels of thermal recover of this unit and condenser can both independently be accomplished the discharging of condensation heat respectively, have improved the condensation ability of unit greatly, realize cold and hot discharging more easily; Therefore; When guaranteeing the normal operation of refrigeration, can improve refrigerating efficiency, realize the efficient utilization of energy.When realizing whole recuperation of heat, the total Energy Efficiency Ratio of cold and hot amount in summer reaches existing source pump separately all more than the twice of refrigeration efficiency ratio.Its energy-saving effect highly significant.
(3) when whole realization recuperation of heat, the blower fan of air-cooled condenser can be out of service, becomes the condenser that freely dispels the heat, and not only saves the energy consumption of blower fan, goes back condenser and can realize the cold excessively of cold-producing medium.When guaranteeing the normal operation of refrigeration, can improve refrigerating efficiency greatly, realize the efficient utilization of energy.
2, heat pump mode
Air-conditioning heats to heat with the domestic hot-water and carries out pattern simultaneously:
The high temperature and high pressure gaseous refrigerant of compressor outlet at first gets into first order recover, carries out heat exchange, owing to be in compressor outlet, the temperature of cold-producing medium is high, and therefore, first order heat exchanger will obtain heat of high temperature, produce the higher domestic hot-water of leaving water temperature.Cold-producing medium gets into second level heat regenerator more then; A remaining condensation heat part is used to heat the hot water supply system that second level heat exchanger is connected; Cold-producing medium further is cooled, and a mouth from four-way change-over valve gets into afterwards, and the c mouth flows out; Get into again in the condenser (be evaporimeter summer), for air-conditioning system provides heat.In condenser (be evaporimeter summer), cold-producing medium is become liquid by total condensation, get into the expansion valve step-down again after; Getting into evaporimeter 5 (be air-cooled condenser summer) again absorbs heat and becomes the low-temp low-pressure gaseous refrigerant; Get into the cross valve reversal valve afterwards, got into by the b mouth, the d mouth flows out; Return compressor at last, accomplish kind of refrigeration cycle.
The characteristics of winter mode:
Winter air-conditioning and hot water supply system perhaps do not need heat simultaneously simultaneously, and unit provides heating capacity according to the required total heat of hot-water heating system at any time.
3, transition season pattern: refrigeration is freely selected operation with two kinds of patterns of heat pump
When air conditioner refrigerating is little, the hot water heating capacity is big, can in refrigeration and two kinds of patterns of heat pump, freely select operation, perhaps adopts many units to arrange in pairs or groups according to different pattern of summer in winter and moves.The application freedom and flexibility of unit in system.
Conclusion: by on can know; The superthermal solar heat pump assembly that freely reclaims of my utility model; The connected mode of utilizing the two-stage series connection heat regenerator to connect with condenser can be implemented in the maximization of when freezing summer condensation heat being recycled, and has obvious energy-saving effect and economic well-being of workers and staff.Can be respectively at first order heat regenerator and second level heat regenerator place according to freely obtaining hot water with heat demand, the hot water of different temperatures can also be provided according to demand.Winter, winter, condenser also simultaneously can provide air-conditioning needed hot water except the two levels of thermal recover provides the hot water of different temperatures.One machine all-year-around cooling heat.This structural texture is simple, and control is simple, only when summer in winter pattern is changed, need change cross valve.Be applicable to hot summer and warm winter zone and Xia Redong cryogenic region.It is the high-efficiency and energy-saving type air source heat recovery heat pump device of a kind of anhydrous consumption, no stove hear rate, clean environment firendly.
