Description
Technical field
The present invention relates to refrigerating field and baking heating field, definite a kind of refrigerating plant 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.
Summary of the invention
A kind of refrigerating plant provided by the invention is exactly in order to solve the disappointing and drainage phenomenon that above existing heat pump occurs.
A kind of refrigerating plant, this device comprise condenser, high pressure fluid reservoir, choke valve, evaporimeter, low-pressure liquid storing tank, compressor, high-pressure circulation pump, low pressure recycle pump and circuit control section; The liquid outlet of said condenser is connected on the high pressure fluid reservoir, and one of the outlet of high pressure fluid reservoir is through getting into evaporimeter behind the choke valve, another outlet through behind the high-pressure circulation pump and the pipeline that from compressor, comes out get in the condenser again after merging; The gas outlet of evaporimeter is connected on the low-pressure liquid storing tank; One of low-pressure liquid storing tank outlet inserts behind the low pressure recycle pump and the pipeline that from choke valve, comes out is recycled in the evaporimeter again after merging; After inserting compressor, another outlet gets into condenser; The circuit control section is being controlled the electrical equipment break-make of whole device; So just formed a kind of refrigerating plant, solved some drawbacks of existing heat pump refrigerating device, improved refrigerating efficiency through the high pressure fluid reservoir and the circulating pump of low-pressure liquid storing tank and inside thereof that adds.All there is gas-liquid separation device said high pressure fluid reservoir and low-pressure liquid storing tank inside, make gaseous state condensing agent and liquid condensation agent obvious layering occur, and high-pressure circulation pump and low pressure recycle pump all are to adopt to carry gaseous state and liquid Gas-liquid pump simultaneously in addition.
Also use air conditioner heat pump system to be example; In original heat pump, add high pressure fluid reservoir and low-pressure liquid storing tank device; The high pressure fluid reservoir makes partial circulating of condensing agent formation in the condenser; The liquid condensation agent of heat radiation gets in the partial circulating that evaporimeter and low-pressure liquid storing tank form through throttling arrangement fully; And do not have the gaseous state condensing agent of heat radiation in the high pressure fluid reservoir, to get into condenser through passing through circulating pump after the gas-liquid separation device separation, and need not be once more to just directly use of these gaseous state condensing agent actings, this has also just been avoided the waste of the merit that disappointing phenomenon produced; And in the partial circulating that low-pressure liquid storing tank and evaporimeter are formed; The gaseous state condensing agent of heat absorption is sent in the partial circulating of condenser and high pressure fluid reservoir composition after being compressed the machine compression after the gas-liquid separation device separation in low-pressure liquid storing tank 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.
