Description

The combined refrigerating plant of a kind of heat pipe hot pump
Technical field
The present invention relates to refrigerating field and baking heating field, the definite combined refrigerating plant of a kind of heat pipe hot pump of saying so.
Background technology
Under current social condition, heat pump techniques is the new energy technology that receives much attention in the whole world in recent years." pump " that people were familiar with is a kind of plant equipment that can improve potential energy, mainly is that water is extracted into a high position from low level such as water pump.And " heat pump " is a kind of low grade heat energy that can from natural air, water or soil, obtain, and through the electric power acting, providing can be by the device of the used high-grade heat energy of people.
Heat pump is the device that a kind of heat energy with low-temperature heat source is transferred to high temperature heat source.The low-temperature heat source that is generally used for heat pump assembly is medium---air, river, the seawater around ours, or from the equipment of industrial product, discharges assistant engineer's matter, and the normal and surrounding medium of these working medium has the temperature that is close.The operation principle of heat pump assembly is consistent with compression refrigerating machine; In packaged air-conditioner,,, all be to use same set of equipment to accomplish in summer air-conditioning cooling or heating in the winter time in order to give full play to its usefulness.When warming oneself in the winter time, evaporimeter in the sky temperature device and condenser are assigned a new job through a reversal valve.
When summer air-conditioning is lowered the temperature, press the cooling condition operation, by the high pressure condensing agent steam of compressor discharge; Get into condenser, refrigerant vapour is condensed into liquid, gets into evaporimeter through throttling arrangement; And in evaporimeter, absorb heat, with the room air cooling, the refrigerant vapour after the evaporation is compressed machine and sucks; Go round and begin again like this, realize kind of refrigeration cycle.When warming oneself in the winter time, so the high pressure refrigerant vapor of being discharged by compressor flows into indoor evaporator (do condenser with); The latent heat of emitting during the refrigerant vapour condensation with the room air heating, reaches the heating of house purpose; Condensed liquid refrigerant is crossed throttling arrangement from reverse flow and is got into condenser (do evaporimeter with), absorbs external heat and evaporates; Steam after the evaporation is compressed machine and sucks, and accomplishes to heat circulation.Like this, the heat " pump " in the outside air (or recirculated water) is gone into higher indoor of temperature, so be called " heat pump ".
This is general in the market heat pump techniques, though very ripe, because the bore problem of heat exchange copper tube in A/C evaporator and the condenser; When summer air-conditioning is lowered the temperature, press the cooling condition operation, by the high pressure condensing agent steam of compressor discharge; Get into condenser, refrigerant vapour is condensed into liquid, gets into throttling arrangement then; The condensing agent that gets into throttling arrangement is liquid for best in theory; But heat pump gets into the condensing agent of throttling arrangement when practical operation be not liquid entirely, possibly have disappointing phenomenon, and the gaseous state condensing agent of the disappointing process just of what is called compressor high pressure compressed does not all dispel the heat in condenser and cools off liquefy; And the condensing agent of liquefy does not under high pressure flow to throttling arrangement along with the liquid condensation agent yet; This part high-pressure gaseous condensing agent decompression back so just occurs and got in the evaporimeter, can not in evaporimeter, gasify also just impossible absorption refrigeration indoor temperature; Let alone do useful work, so compressor occurred the acting of this part gaseous state condensing agent is wasted fully.The liquid condensation agent gets into evaporimeter, and in evaporimeter, absorbs heat, and room air is cooled off; Refrigerant vapour after the evaporation is compressed machine and sucks, and owing to be mechanical action, can not guarantee not have the liquid condensation agent to be compressed the machine income; Heat of vaporization becomes gaseous state in the absorption chamber and the liquid condensation agent that these are inhaled into does not have; That is to say that this part liquid condensation agent also is not make useful work just to have got into compressor again and be transported in the condenser, this phenomenon is called drainage, goes round and begins again like this; Constantly take place to lose heart and the drainage phenomenon, and these phenomenons are also with the waste of part mechanical power.And when warming oneself in the winter time, condenser and evaporimeter are interchange reaction, and explanation so just is as long as air-conditioning just exists the waste of this part mechanical power in operation.
And air conditioner is an application facet of heat pump; All using heat pump aspect wine-making industry, pharmacy industry, barn part, the hot water heating etc. at present; And the heat pump of these aspects all with air-conditioning in heat pump the same; Exist and lose heart and the drainage phenomenon, also just exist the waste of idle work.
Hot pipe technique in refrigeration (heat) field begins development with heat pump techniques basically jointly, and heat pipe heat exchanging belongs to hot fluid and the non-touching surface-type heat exchanger of cold fluid.Its main feature is: simple in structure, heat exchange efficiency is high, can directly utilize interior heat-exchange working medium self the physical property value of heat pipe to accomplish to send automatically basically and pass heat, and it is little to consume auxiliary power.Transmit under the condition of identical heat, the power consumption of the metal of heat exchange of heat pipe is less than the heat exchanger of other types; Pressure loss when heat exchanging fluid passes through heat exchanger is littler than other heat exchangers.Automatically carry out though heat pipe heat exchanging is energy-conservation fully basically, hot pipe technique still has significant limitation, use hot pipe technique must guarantee that the indoor and outdoor temperature difference is very big, and this point has directly just limited the large tracts of land popularization of hot pipe technique; When using hot pipe technique in addition; The flow properties problem of heat transferring medium in the middle of heat exchanger in the hot-pipe system must meet wherein; The high and low position difference problem of two heat exchangers in the time of just must considering the hot-pipe system operation, a limitation when this also is the hot-pipe system use.

The combined refrigerating plant of a kind of heat pipe hot pump, this device comprise condenser, triple valve, choke valve, check valve, circulating pump one, circulating pump two, evaporimeter, fluid reservoir, magnetic valve, compressor and circuit control section; Said condenser, triple valve, choke valve, evaporimeter, fluid reservoir and compressor are cascaded in order, have formed a heat pump refrigerating circulation; Said magnetic valve is connected in parallel on the compressor, and opens solenoid valve in the time of can making compressor out of service so still keeps systemic circulation; Said circulating pump one inserts from the 3rd interface of said triple valve, gets in the fluid reservoir then; Said circulating pump two and check valve are connected on the lower end of fluid reservoir and choke valve, form another loop, have so just formed the combined refrigerating plant of a kind of heat pipe hot pump.
Also use air conditioner heat pump system to be example; In original heat pump, add two circulating pumps; These two circulating pumps are to use the Gas-liquid pump that can carry gas and liquid simultaneously; And also added in the fluid reservoir can be the gas-liquid separation device of the obvious layering of gas-liquid; Circulating pump condensing agent in making condenser forms a partial circulating like this, and the liquid condensation agent of heat radiation gets in the partial circulating that evaporimeter and fluid reservoir form through throttling arrangement fully, and not have the gaseous state condensing agent of heat radiation under being driven by circulating pump one, in fluid reservoir, to get into condenser after the separation of process gas-liquid separation device; Need not just directly use these gaseous state condensing agent actings once more, this has also just been avoided the waste of the merit that disappointing phenomenon produced; And in the partial circulating that fluid reservoir and evaporimeter are formed; The gaseous state condensing agent of heat absorption is sent in the partial circulating of condenser and fluid reservoir composition after being compressed the machine compression after the gas-liquid separation device separation in fluid reservoir fully, and the liquid condensation agent that does not have heat absorption to become gas is used to reduce indoor temperature through getting into next partial circulating in the circulating pump entering evaporimeter again.
It more than is the simple principle that this device uses heat pump work refrigeration; This invention realizes energy-saving heat-pipe refrigerating through the magnetic valve that on compressor, inserts parallel connection; When using heat-pipe refrigerating, close compressor is opened magnetic valve; The miscellaneous part operation is identical with heat pump work refrigeration mode, has so just realized starting the energy-saving heat pipe pattern that compressor just can freeze.
This device not only can single cooling and warming; And after on this device two cross valves being installed; All right cooling and warming simultaneously; One or two interface of cross valve is communicated with the air inlet of condenser and the gas outlet of evaporimeter, and one two other interface is connected on the convergence tube place of magnetic valve and compressor, an exit that connects fluid reservoir; 2 two interfaces of cross valve are communicated with the liquid outlet of condenser and the inlet of evaporimeter; Interface that is connected on triple valve of two other interface; What another was connected on check valve and choke valve converges the pipeline place, adds behind two cross valves cooling and warming simultaneously like this.Said circuit control section is being controlled the circuit logic computing and the equipment run switch of whole device, can realize the automation start and stop as required.
