Background technology
For the environment that needs year round cooling, what adopt at present is conventional air conditioner.Because conventional air conditioner is standard production manufacturing routinely, type selecting is by peak load, though can satisfy wide weather service requirement, but in lower spring of outside air temperature, autumn, three seasons of winter, the operational factor that still need simulate summer guarantees the stable of indoor temperature, humidity, when moving in anti-season, causes the air-conditioning system unit efficiency low, the energy consumption height, What is more, and unit can not normally move.
At present, in the air-conditioning system of whole year operation, conventional air conditioner need be moved the compression refrigeration circulation.In traditional air-conditioning system, for spring, autumn, three season of winter outside air temperature lower, and the high enclosed environment that needs cooling of indoor temperature at present, utilizes outdoor cold source cooling indoor environment to mainly contain following four kinds of modes:
(1) adopts packaged air conditioner
Packaged air conditioner belongs to Air Conditioner, is used to purify air, and regulates temperature and humidity.It is with after self-checking device cooperates, and can guarantee that the room air parameter strictly controls within the specific limits.Be provided with outdoor new wind air-valve and indoor circulation air-valve in the unit.The outdoor new wind that enters from outdoor new wind air-valve and mix from the indoor return air that the indoor circulation air-valve enters after, through primary efficient filter screen and medium air filtration net filtration dust, improve its relative humidity by humidifier again, be sent to indoor the refrigeration by blower fan at last.
Packaged air conditioner is fit to large-scale machine room, and investment is big, and floor space is big, equipment complexity, control accuracy height.The ventilating system complexity.
(2) ventilation adds air-conditioning system
Draw outdoor new wind and deliver to the machine room cooling after filtration behind the net filtration dust, this system equipment is simple, invests for a short time, and control accuracy is low.Ventilating system is stopped up screen pack easily, and screen pack stops up the back influences ventilation effect, is difficult to guarantee the cleanliness factor of environment.
(3) air-air heat exchanger adds air-conditioning system
Outdoorly new distinguished and admirablely carry out heat exchange through heat exchanger and indoor circulation wind.This scheme has solved the low problem of environment control accuracy, but the volume of air-to-air heat exchanger is bigger, invests also bigger.The air-air heat-exchange system is also stopped up screen pack easily, and screen pack stops up the back influences the ventilation heat exchange effect.
(4) air-conditioner
This mode can satisfy the control of environment high accuracy, and winter, unit starting was frequent, and the comprehensive energy consumption height.
In sum, adopt, be difficult to the requirement of satisfied temperature, humidity, cleanliness factor to the new wind of indoor introducing.The four seasons are moved then comprehensive energy consumption height of traditional air-conditioning.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly can utilize outdoor lower air to do low-temperature receiver, improves the operational efficiency of air-conditioner, reduces the refrigerating circulatory device of the band injector of compressor power consumption.
The utility model adopts following technical scheme:
The utility model comprises and is used to suck and the compressor of compressed gaseous refrigeration working medium, utilize the injector of the pressure energy injection low pressure liquid refrigeration working medium of high-pressure gaseous refrigeration working medium, be used for the evaporimeter that carries out the condenser of heat exchange and be used between refrigeration working medium and room air, carrying out heat exchange between refrigeration working medium and the outdoor air, at compressor, dispose injector between condenser and the evaporimeter, the outlet of compressor links to each other with the import of injector gases at high pressure, the outlet of condenser links to each other the gas of injector with the import of injector low pressure liquid, the outlet of liquid mixture links to each other with evaporator.
The gas-liquid separator that the utility model is used for refrigeration working medium is divided into gas refrigeration working medium and liquid refrigerating working medium links to each other with compressor inlet, and the air accumulator that is used to store the Compressed Gas refrigeration working medium links to each other with compressor outlet.
The utility model good effect is as follows: the utility model can utilize outdoor lower air to do low-temperature receiver in lower spring of outside air temperature, autumn, three seasons of winter, by operation injection refrigeration mode, both guaranteed the stable of indoor temperature, humidity, improved the operational efficiency of air-conditioner again, reduce consumption of compressor, reach energy-saving effect preferably.
The utility model removes necessary assembly with respect to traditional refrigerating plant, outside compressor, evaporimeter, the condenser, has increased injector.The utility model is suction, heat release parts with the evaporimeter and the condenser of traditional aircondition, with refrigeration working medium as the phase-change heat transfer medium, a small amount of gases at high pressure with compressor are power promotes liquid in the condenser by injector pressure, the circulation of promotion refrigeration working medium is to reach the purpose of taking away indoor heat.Save most of power consumption of compressor in the air conditioner refrigerating, greatly reduced the manufacturing cost and the operating cost of device.
