Abstract
The invention relates to an atomizing evaporating system for low-temperature heating of an air source heat pump and an air conditioner, comprising a compressor, a heat exchanger, a liquid storage tank, an expansion valve, an atomizing evaporator and an evaporator. The heat energy dissipated normally by the exhaust pip of the compressor is utilized, the liquid drops are atomized and evaporated by the sandwich layer of the evaporator, no electric heating and other auxiliary energy is used, and the evaporation cost is reduced. In addition, the one-time atomizing evaporating is adopted on the basis of the one-time evaporating by the evaporator of the existing system, so that two-time evaporating is realized. Due to the adoption of the two-time evaporating, the low-temperature gas-liquid refrigerant medium is fully evaporated, the evaporating efficiency is improved, and sufficient refrigerant gas is supplied to the compressor of an air conditioner for low-temperature heating, so that the compressor can heat normally and stably at the low temperature of lower than 5 DEG C below zero, and the efficiency of heating by the heat pump of the air conditioner at the low temperature of lower than 5 DEG C below zero is guaranteed.
Description
Technical field
The present invention relates to air source heat pump, air-conditioner low-temperature heating field, is a kind of spray evaporation system for air source heat pump, air-conditioner low-temperature heating specifically.
Background technology
The operation principle of air source heat pump and air-conditioning be utilize the characteristic of coolant media low-temperature evaporation (as R22 under the low temperature of-46 DEG C with regard to start vaporizer), by the air-introduced machine on evaporimeter, airborne heat being sucked to evaporimeter enters in evaporator fin setting-in, coolant media in copper pipe absorbs airborne heat and evaporates, making the liquid evaporation in refrigerant gas liquid mixture is that gas enters compressor, the gas that produces HTHP through compressor compression heats, and the equipment that now high temperature and high pressure gas produces hot blast or cold wind through condenser heat radiation is commonly referred to as air-conditioning; If this high temperature and high pressure gas produces the equipment of hot water or cold water through heat exchanger heat exchange, be commonly referred to air source heat pump.
Air source heat pump and air-conditioning just can not normally heat lower than-5 DEG C in environment temperature at present, its reason is: the heat that common air-conditioning evaporimeter absorbs from air is at low temperatures few, needed enough refrigerant tolerance when being not enough to evaporate compressor and normally heating, thereby cannot reach condition and the requirement that compressor normally heats, so DEG C do not heat below in low temperature-5, in addition, at present low-temperature air energy heat pump must corresponding increase system disengagement area in order to increase evaporation capacity, thereby has increased product cost.
Summary of the invention
In view of above-mentioned, the object of the present invention is to provide the spray evaporation system of a kind of air source heat pump, air conditioner low temperature heating.
The present invention is achieved through the following technical solutions:
For a spray evaporation system for air source heat pump, air-conditioner low-temperature heating, formed by compressor, heat exchanger, fluid reservoir, capillary, spray evaporator and evaporimeter, coolant media is passed to heat exchanger via the outlet of spray evaporator outer tube; Be passed to capillary by heat exchanger; Be passed to evaporimeter by capillary; Be passed to fluid reservoir by evaporimeter; Be passed to compressor by fluid reservoir; Finally be passed to the outer tube inlet of spray evaporator, circulating transfer by compressor; Another road coolant media is passed to heat exchanger via the outlet of spray evaporator outer tube; Be passed to tube inlet in spray evaporator by heat exchanger; Via the pressure nozzle in spray evaporator, gas-liquid mixed coolant media is sprayed into microatomization drop; Be passed to fluid reservoir by the outlet of spray evaporator inner tube again; Be passed to compressor by fluid reservoir; Finally be passed to the outer tube inlet of spray evaporator, circulating transfer by compressor.
Cyclic high-temperature coolant media in the outer pipeline of above-mentioned spray evaporator 1;
Circulating refrigerant medium in the interior pipeline of above-mentioned spray evaporator 1.
Operation principle of the present invention is:
After gas under the duty of compressor low-temperature heating after compressed intensification enters condenser or heat exchanger heat exchange by blast pipe, become the coolant media of gas-liquid mixed.
Now in system, before capillary, be the gas-liquid mixed coolant media of high pressure low temperature, it will shunt a part through spray evaporator, under system high pressure herein, pressure nozzle in spray evaporator, by the ejection of gas-liquid mixed refrigerant, forms fog-like liquid fine droplets shape; The high-temperature gas producing due to compressor has entered the interlayer of spray evaporator through blast pipe, directly entering fluid reservoir after the refrigerant drop endothermic gasification of atomization, then enter the air inlet of compressor in moment; The gas-liquid mixed coolant media that another road becomes low-pressure low-temperature after capillary step-down enters evaporimeter, absorbed heat from air by evaporimeter and it is evaporated to gas enters fluid reservoir and enter again compressor inlet, so just there is two parts gas to enter compressor, thereby increased the air inflow of compressor.
Because spray evaporator and heat pump carry system evaporator twice evaporation, the gas-liquid coolant media under low temperature is evaporated fully, improve evaporation performance, heat at low temperatures the cold media gas that provides enough to compressor of air conditioner, thereby realized compressor (5 DEG C following) normal stable heating at low temperatures.
Advantage of the present invention and beneficial effect:
1, spray evaporator utilization of the present invention is the heat energy of the normal heat radiation of compressor exhaust pipe, by the interlayer evaporation atomized drop of evaporimeter, does not need other supplementary energies such as newly-increased electrical heating, reduces evaporation cost.
2, spray evaporator of the present invention utilizes shower nozzle effect, by the gas-liquid mixed coolant media atomization of high pressure low temperature, is conducive to or has accelerated the gasification of moment refrigerant drop.
3, the present invention is dividing two-way through the high pressure low temperature gas-liquid mixed coolant media of heat radiation or heat exchange, one tunnel is through spray evaporator, evaporate through normal system on another road, thereby reduce by the evaporation coolant quantity of evaporimeter, the disengagement area that equals in a disguised form to have increased evaporimeter, has reduced system cost.
4, the present invention is the heat pump type air conditioning system that spray evaporator has been installed, and does not need to configure the dedicated compressor of the three special hole low-temperature heatings that price is higher, has simplified technique, has reduced product cost.
5, the present invention is by the flush distillation device evaporation of existing system, increase again a spray evaporation, become twice evaporation, twice evaporation is evaporated the gas-liquid coolant media under low temperature fully, improve evaporation performance, heat at low temperatures the cold media gas that provides enough to compressor of air conditioner, thereby realized compressor (5 DEG C following) normal stable heating at low temperatures, ensured the usefulness that under the low temperature of air-conditioning heat pump, (5 DEG C following) heats.
