Description

A kind of heat pipe hot pump combination type refrigerating plant
Technical field
The present invention relates to refrigerating field and Baking out field, be specifically a kind of heat pipe hot pump combination type refrigerating plant.
Background technology
When society, heat pump techniques is the new energy technology received much attention in the whole world in recent years. " pump " that people are familiar with is a kind of plant equipment that can improve potential energy, and such as water is mainly extracted into a high position from low level by water pump. And " heat pump " is a kind of low grade heat energy that can obtain from the empty gas and water of nature or soil, do work through electric power, it is provided that can the device of high-grade heat energy used by people.
Heat pump is a kind of device by the heat energy transfer of low-temperature heat source to high temperature heat source. The low-temperature heat source being generally used for heat pump assembly is the medium air around us, river, sea water, or discharges assistant engineer's matter from the equipment of industrial product, these working medium often and surrounding medium there is the temperature being close. The operation principle of heat pump assembly is consistent with compression refrigerating machine; In packaged air-conditioner, in order to give full play to its usefulness, lower the temperature at summer air-conditioning or warm oneself in the winter time, all using same set of equipment to complete. When warming oneself in the winter time, the vaporizer in empty temperature device is assigned a new job by a reversal valve with condenser.
When summer air-conditioning is lowered the temperature, run by cooling condition, the high pressure condensing agent steam discharged by compressor, enters condenser, and refrigerant vapour is condensed into liquid, vaporizer is entered through throttling arrangement, and absorb heat in vaporizer, room air is cooled down, the refrigerant vapour after evaporation is sucked by compressor, so go round and begin again, it is achieved kind of refrigeration cycle. When warming oneself in the winter time, then the high pressure refrigerant vapor discharged by compressor, flow into indoor evaporator (being used as condenser), the latent heat released during refrigerant vapour condensation, heats room air, reach heating of house purpose, condensed liquid refrigerant, enters condenser (being used as vaporizer) from flowing counterflow through throttling arrangement, absorbs external heat and evaporate, steam after evaporation is sucked by compressor, completes to heat circulation. So, the heat " pump " in outside air (or recirculated water) is entered the indoor that temperature is higher, therefore is called " heat pump ".
This is general in the market heat pump techniques, although it is very ripe, but due to the bore problem of heat exchange copper tube in A/C evaporator and condenser, when summer air-conditioning is lowered the temperature, run by cooling condition, the high pressure condensing agent steam discharged by compressor, enter condenser, refrigerant vapour is condensed into liquid, subsequently into throttling arrangement, the condensing agent of entrance throttling arrangement is liquid in theory is best, but heat pump enters the condensing agent of throttling arrangement and is not all liquid when practical operation, would be likely to occur disappointing phenomenon, so-called lose heart namely through the gaseous state condensing agent of compressor high pressure compressed not within the condenser all coolings become liquid, and the condensing agent not becoming liquid under high pressure flows to throttling arrangement also with liquid condensation agent, enter after thus occurring in that the decompression of this partial high pressure gaseous state condensing agent in vaporizer, can not gasify in vaporizer, also absorption refrigeration indoor temperature it is impossible to, let alone do useful work, so occurring in that the acting of this part gaseous state condensing agent is wasted by compressor completely. liquid condensation agent enters vaporizer, and absorb heat in vaporizer, room air is cooled down, refrigerant vapour after evaporation is sucked by compressor, and owing to being mechanical action, do not ensure that and do not have liquid condensation agent to be taken in by compressor, and the liquid condensation agent that these are inhaled into does not have heat in absorption chamber and flashes to gaseous state, that is this operative liquid condensing agent is also do not make useful work just entered again compressor and be transported in condenser, this phenomenon is called drainage, so go round and begin again, constantly occur to lose heart and drainage phenomenon, and these phenomenons are also with the waste of some mechanical merit. and when warming oneself in the winter time, condenser and vaporizer are interchange reaction, as long as so namely illustrating that air-conditioning is running the waste existing for this some mechanical merit.
And air conditioner is an application aspect of heat pump, at present all use heat pump in wine-making industry, pharmacy industry, barn part, hot water heating etc., and the heat pump of these aspects is all the same with the heat pump in air-conditioning, also exist and lose heart and drainage phenomenon, also exist for the waste of idle work.
Hot pipe technique in refrigeration (heat) field substantially jointly starts development with heat pump techniques, and heat pipe heat exchanging belongs to hot fluid and the non-touching surface-type heat exchanger of cold flow body. It is mainly characterized by: simple in construction, and heat exchange efficiency is high, substantially can directly utilize heat-exchange working medium own physical value in heat pipe and accomplish automatically to send and pass heat, consume auxiliary power little. When transmitting identical heat, the metal of heat exchange of heat pipe consumes energy less than other kinds of heat exchanger; Pressure loss when heat exchanging fluid is by heat exchanger is less than other heat exchangers. Automatically carrying out although heat pipe heat exchanging is substantially completely energy-conservation, but hot pipe technique has significant limitation, indoor and outdoor temperature difference is very big to use hot pipe technique must assure that, and this point directly limits the spread of hot pipe technique; When additionally using hot pipe technique, heat exchanger in hot-pipe system has to comply with the flow properties problem of wherein intermediate heat transfer medium, namely must take into the high and low position difference problem of two heat exchangers when hot-pipe system runs, this is also limitation during hot-pipe system use.
