Description

A kind of air conditioner of heat energy that has backheat
Technical field
The present invention relates to a kind of conditioner, the particularly a kind of low-temperature heat source of nature existence or conditioner that thermals source such as industrial exhaust heat, used heat promote compressor operation of utilizing.
Background technology
In the New Times that China's energy is changed, people are worrying for the security of environmental protection, energy shortage, electricity shortage, national energy strategy and the problems such as economy of using energy source.And aircondition is used the rich and influential family of energy beyond doubt, and aircondition major part is in the market come the running of drive compression machine by electric power.The aircondition that also exists some to utilize heat energy to drive, present on the market GHP gas heat pump air-conditioning for example is the compressor that utilizes gas engine to drive to be equipped in off-premises station.And there is a large amount of heat energy in occurring in nature, for example solar energy, geothermal energy etc., and in addition, a large amount of industrial exhaust heats, automobile waste heat are discharged in the air, and this not only causes the waste of the energy, also contaminated environment.Utilization for this part heat energy, high temperature heat source generates electricity in also only limiting at present utilize, and the limitation of this way is that a large amount of low-temperature heat source (50 ℃-150 ℃) is not utilized effectively, and the utilization of the electric power that the needs consideration sends, problems such as transmission ﹠ distribution are incorporated into the power networks.
Summary of the invention
Be defective and the deficiency that overcomes prior art, the invention provides a kind of aircondition that utilizes low-temperature heat source to promote compressor operation.Effectively utilize discarded low-temperature heat source, alleviating energy crisis, and the power that produces is directly used in drives compressor of air conditioner and carry out cooling and warming, get on the spot can, use on the spot, needn't consider the electric power transportation problem.
The present invention is achieved by the following technical solutions, and in this conditioner, off-premises station comprises compressor, cross valve, outdoor heat converter (1 or many), outdoor expansion valve, bypass and plate type heat exchanger.Indoor set comprises indoor heat converter (1 or many) and indoor expansion valve.Utilize the switching of cross valve, when refrigerating operaton, outdoor heat converter is equivalent to condenser, and indoor heat converter is equivalent to evaporimeter, and the evaporation heat absorption that utilizes cold-producing medium is with indoor refrigeration.When cross valve switches to when heating state, outdoor heat converter is equivalent to evaporimeter, and indoor heat converter is equivalent to condenser, utilizes the condensation of refrigerant heat release with indoor heating.
The compressor of this conditioner is not or does not rely on electric power to drive entirely, but utilize a turbine to drive, described turbine is connected on the power set of a cover based on the organic Rankine circulation, and these power set comprise evaporimeter, turbine, condenser and circulating pump.By pipeline these four parts are linked to be the loop in order, cycle fluid circulates in the loop.
When system works, the cycle fluid evaporimeter of flowing through, absorb the heat of external heat source after vaporization become high steam, the high steam acting of in turbine, expanding, the merit amount of output passes to compressor.Steam after the acting becomes the exhaust steam of low-temp low-pressure.Consider that this exhaust steam still has the recyclable utilization of certain heat, the present invention is provided with the plate type heat exchanger that makes compressor suction side cold-producing medium and described exhaust steam carry out heat exchange.To be communicated to a triple valve V1 through the exhaust steam after the turbine expansion acting, this triple valve V1 have with described exhaust steam import described power set condenser first opening and described exhaust steam is imported second opening of described plate type heat exchanger.Described triple valve V1 is the electrodynamic type triple valve, described exhaust steam can be entered condenser through first opening, is condensed into liquid state after circulating pump is sent liquid refrigerant into evaporimeter and carries out new circulation; Also described exhaust steam can be entered the described plate type heat exchanger of suction side through second opening, exhaust steam and compressor suction side cold-producing medium carry out after the heat exchange, be communicated to second triple valve V2 again, this triple valve V2 is the electrodynamic type triple valve, have with described exhaust steam import described power set condenser first opening and described exhaust steam is imported second opening of described aircondition outdoor heat converter.During refrigerating operaton, described exhaust steam is imported described condenser through first opening, be condensed into liquid state after circulating pump is sent liquid refrigerant into evaporimeter and carry out new circulation; During heating operation, described exhaust steam can be imported described outdoor heat converter through second opening, carry out entering described condenser again after the heat exchange, be condensed into liquid state after circulating pump is sent liquid refrigerant into evaporimeter and carry out new circulation with refrigerant.
The evaporimeter of described power set is a heat-exchange device, and in this heat-exchange device, the origin of heat that cycle fluid absorbs is in the existing thermal source of nature, and for example solar energy, geothermal energy perhaps derive from industrial exhaust heat used heat etc.Can adopt totally-enclosed, semiclosed between these power set and the compressor or begin to be connected, when the merit quantity not sufficient of this power set output when satisfying the cooling and warming demand, can replenish with electric power and come the drive compression machine.
The invention has the beneficial effects as follows:
1. utilize discarded low-temperature heat source to drive the aircondition running, thereby realize energy-saving and emission-reduction.
2. the employing heat reclamation device improves cooling and warming efficient.
3. the power of Chan Shenging is directly used in and drives compressor of air conditioner and carry out cooling and warming, get on the spot can, use on the spot, needn't consider the electric power transportation problem.
