Description

Three cold source air conditioning groups
Technical field
The invention belongs to air conditioner refrigerating field, and in particular to reclaim three cold source air conditioning groups of heat energy.
Background technology
The existing Air-Cooled Heat Pump Unit summer that can provide domestic hot-water provides air conditioning water, and winter provides air conditioner heat Water, whole year can provide domestic hot-water.It carries two condensers:Air-cooled condenser and water heater, air-cooled condenser summer to Condensation heat is discharged in air, winter is converted into evaporator and absorbed heat from air, when non-air-conditioning season needs to provide domestic hot-water, wind Cool condenser absorbs heat as evaporator from air.Water heater is heated originally as condenser whole year using refrigerant condensation heat Water.Therefore, the Air-Cooled Heat Pump Unit with water heater only has two low-temperature receivers of air and running water.
Production, life, work in, having to contain in many waste gas, waste water has substantial amounts of heat energy not recycle, but with Meaning is discharged into environment, is wasted the energy, is polluted environment.Such as:In food cooking manufacturing process, kitchen will consume largely Fuel, produce substantial amounts of high-temperature oil smoke waste gas and washes, oil smoke is discharged to outdoor by smoke exhaust ventilator, enclosure, and washing is useless Water is discharged into sewer, and heat energy therein is also discharged, do not recycled therewith, and fume pollution air, it is also desirable to Energy heats hot wash-water, air conditioning hot, therefore waste mass energy.Nature has substantial amounts of surface water and groundwater, summer Cooling water can be provided season for source pump, winter can be as the thermal source of source pump.But existing Air-Cooled Heat Pump Unit These waste gas, waste water and natural water body can not be utilized.
The content of the invention
It is able to can both be utilized again useless by the use of air and running water as low-temperature receiver it is an object of the invention to provide a kind of The three cold source air conditioning groups of gas, waste water and natural water body as low-temperature receiver.
The present invention solution be:Three cold source air conditioning groups include air-cooled condenser, water-cooled condenser, water heater, sky Evaporator, compressor, expansion throttling device, change working device, servicing unit are adjusted, they are in turn connected into heat pump.Air-conditioning steams The side that device is mounted in expansion throttling device is sent out, air-cooled condenser, water-cooled condenser are mounted in the opposite side of expansion throttling device;Air-conditioning evaporates Device summer provides chilled water or cold wind for air-conditioning system, and winter is converted into condenser, and hot water or hot blast are provided for air-conditioning system.Wind Cool condenser, water-cooled condenser are arranged in parallel or in series in heat pump, between expansion throttling device and four-way reversing valve, both With identical operating mode, while it is condenser, or is evaporator simultaneously;It is cold that air-cooled condenser summer discharges refrigerant into air Solidifying heat, winter are converted to evaporator, absorbed heat from air;Water-cooled condenser summer, outwardly cool water media was (waste gas, waste water, natural Water body etc.) in discharge refrigerant condensation heat, winter is converted to evaporator, from extraneous water heat medium (waste gas, waste water, natural water body etc.) Middle heat absorption.Water heater heats running water between the exhaust outlet and four-way reversing valve of compressor, using high temperature refrigerant, no matter Heat pump is that kind of refrigeration cycle or heating circulate, can be as needed, and annual preferential guarantee water heater provides domestic hot-water. When providing domestic hot-water in non-air-conditioning season, A/C evaporator is stopped, and air-cooled condenser, water-cooled condenser are converted to evaporation Device, absorbed heat from air, waste gas, waste water, natural water body, the high temperature refrigerant condensation of heating domestic hot water is provided for water heater Heat.Therefore, refrigerant is (useless with extraneous water cooling heating agent with outdoor air heat exchange, in water-cooled condenser in air-cooled condenser Gas, waste water, natural water body etc.) heat exchange, in water heater with originally hydrothermal exchange, the unit are referred to as three cold source air conditioning groups. When extraneous cold and hot matchmaker is waste gas, using air-water heat exchanger, by heat exchange, the heat energy of waste gas is transported to water-cooled condenser In;When the water body of waste water, natural water body for cleaning, can be delivered directly in water-cooled condenser;When waste water, natural water body are dirt During turbid water body, using water-water heat exchanger, by heat exchange, the heat energy of waste water, natural water body is transported in water-cooled condenser; Because water-cooled condenser is that refrigerant exchanges with circulating water heating, circulating water heating or cooling, in fact, by valve transfer, it Hot and cold water can be provided for air conditioning terminal, when A/C evaporator provides refrigerant for air conditioning terminal, it can be carried for air conditioning terminal Supplying hot water;When A/C evaporator provides heating agent for air conditioning terminal, it can provide cold water for air conditioning terminal, and air-conditioning system can be with Freeze simultaneously and heat.Such as:When large-scale office building depth is larger, inner region whole year needs cooling, and some data center modules are also required to All-year-around cooling, therefore in the winter time, air-conditioning system should heat, and also want cooling, can meet above-mentioned requirements using water-cooled condenser.
Or be combined into one air-cooled condenser, water-cooled condenser, the double low-temperature receiver condensers of a monoblock type are made.The condensation Device takes the form of double-tube heat exchanger, in refrigerant tubing overcoat water pipe, the water flowing in outer tube, circulatory mediator is done with water, profit With the heat energy of waste gas, waste water or natural water body, fin is covered on pipe outer wall, is exchanged heat using outdoor air, refrigerant and overcoat Recirculated water heat exchange in pipe, recirculated water also exchange heat with outdoor air simultaneously, and the condenser is referred to as the double low-temperature receiver condensers of interior tubular type;Or Person, in water pipe overcoat refrigerant tubing, refrigerant is led in outer tube, fin is covered on refrigerant pipe pipeline outer wall, so, refrigeration Agent is exchanged heat using outer tube wall and fin with outdoor air, while can also be exchanged heat by the recirculated water in inner tube, and the condenser claims For the double low-temperature receiver condensers of outer pipe type, because the condenser does low-temperature receiver using water and air, it is referred to as double low-temperature receiver condensers.This pair of low-temperature receiver Condenser compact, make heat pump greatly simplified.
Though above-mentioned three cold source air conditionings group using air-cooled condenser and water-cooled condenser combination or use monoblock type Double low-temperature receiver condensers, the refrigerant in condenser individually can both exchange heat with water or outdoor air, can also simultaneously with water or room Outer air heat-exchange.Refrigerant in water-cooled condenser with extraneous water cooling heating agent heat exchange, during heat pump kind of refrigeration cycle, a part Or whole high temperature refrigerants are taken away in water-cooled condenser with extraneous cool water media heat exchange, condensation heat by extraneous cool water media, when not having When having the flow of extraneous cool water media or extraneous cool water media inadequate, start air-cooled condenser, condensation heat is discharged in air;Heat pump system During controlling thermal cycle, part or all of low temperature liquid refrigerant evaporation endothermic in water-cooled condenser, from extraneous water heat medium Heat energy is absorbed, when the flow of not extraneous water heat medium or extraneous water heat medium is inadequate, starts air-cooled condenser, is inhaled from air Heat.In other words, when extraneous water cooling heating agent can meet double low-temperature receiver condenser all heat exchange demands, outdoor unit ventilating fan does not work, Refrigerant does not exchange heat with outdoor air;It is outdoor when extraneous water cooling heating agent can only meet double low-temperature receiver condenser portion heat exchange demands Machine ventilating fan works, and refrigerant exchanges heat with water and outdoor air simultaneously;When not extraneous water cooling heating agent, outdoor unit ventilating fan work Make, refrigerant exchanges heat with outdoor air, meets double low-temperature receiver condensers all heat exchange demands.A/C evaporator uses air-conditioning water evaporation Device, air conditioner cold and hot water is provided for air conditioning terminal;Or use air-conditioner wind evaporator, there is provided cold-hot wind.
Therefore, three cold source air conditioning groups have following functions:Separate refrigeration, individually heating, independent water heating freeze simultaneously With water heating while heating and water heating while refrigeration and heating and freeze simultaneously, heat, water heating, the unit is fully sharp With air, running water, waste gas, waste water and natural cold and heat source, the used heat of the used heat of architecture noumenon and outdoor environment is comprehensively utilized, Energy-saving effect is notable, is a energy-conservation sharp weapon.
