Description
Technical field
The utility model relates to a kind of energy-conservation air-treatment unit, particularly recycles the air-treatment unit of air draft energy.
Background technology
Along with global warming, in the grandfather lake Group of 8 of hole [global greenhouse gases discharge rate cuts down 50% at least till the year two thousand fifty, with this common objective as all contract states of League of Nations's climatic fluctuation frame group treaty (UNFCC)].Energy-saving and emission-reduction have become the problem that the whole world is paid close attention to.Traditional air-conditioning or be brand-new wind system, or be new return air hybrid system.Though brand-new wind air quality height needs more energy to be used for improving the air-supply quality.And hybrid system, though consume energy unlike brand-new wind, delivery temperature is also mutually far short of what is expected than environment temperature, and the COP of these units is generally about 2.5.
Summary of the invention
At the problem that prior art exists, the utility model provides a kind of air-treatment unit of recycling the air draft energy, has adopted advanced Based Intelligent Control, prevents the phenomenon of blowing a cold wind over, and solves heat exchanger frosting problem.The COP of this unit will reach 3.5.Because new wind, return air are separated, the pollution of having avoided air to mix has improved air quality, meets the standard that the modern pursues high-level quality of life.
The utility model provides a kind of air-treatment unit of recycling the air draft energy.It comprises compressor, four-way change-over valve, evaporimeter, condenser, reservoir, device for drying and filtering, heating power expansion valve, gas-liquid separator, blower fan, motor, frequency converter, pipeline component and control element.This unit separates air draft and air-supply fully, utilizes above-mentioned parts Specialty Design, reasonably optimizing to make the approximate environment temperature that is equal to of temperature of outgoing air, passes to new wind reclaiming energy of exhaust air.According to technique scheme, heat exchanger is evaporimeter and condenser; According to technique scheme, refrigeration and heating process are the transformations by four-way change-over valve, carry out recycled back in the part.
Description of drawings
Figure is a structural representation of the present utility model.
Wherein, the representative of solid arrow direction heats circulation; The dotted arrow direction is represented kind of refrigeration cycle.
The specific embodiment
As shown in the figure, the utility model is related comprises compressor (1), high-voltage switch gear (2), pressure sensor (3), four-way change-over valve (4), first heat exchanger (5), check valve (6), reservoir (7), device for drying and filtering (8), heating power expansion valve (9), second heat exchanger (10), gas-liquid separator (11), low tension switch (12), and it has constituted an air-conditioning heat-exchange system; Exhaust blower, pressure fan, external air channel, cyclelog have constituted air draft and supply air system.This unit comprises heating recycle system and cooling cycle system.
Its cooling cycle system comprises, comes out from compressor (1), by first heat exchanger (5), again by the throttling of expansion valve, enters second heat exchanger (10), gets back to the loop of compressor (1) at last.Process of refrigerastion is shown in dotted line.Summer, ambient temperature was than under the higher state, and extraneous high-temperature gas is handled low-temperature condition, and the air-conditioning unit moves according to kind of refrigeration cycle.Heat exchanger in summer first (5) is made condenser and is used near the air draft side, utilize the refrigeration duty of return air to reduce condenser temperature, and the gas of being convenient to HTHP is in this heat exchange as much as possible.Because energy conservation principle, the condenser heat exchange is many more, and temperature of outgoing air is more near environment temperature, and then the heat that evaporimeter is pulled away is just many more.So freeze by reducing condensation temperature summer.
Its heating recycle system comprises, from compressor (1), by second heat exchanger (10), again by the throttling of expansion valve, enters first heat exchanger (5), gets back to the loop of compressor (1) at last.The process that heats is shown in solid line.Under the lower state of ambient temperature in winter, extraneous cryogenic gas is handled the condition of high temperature, the air-conditioning unit is according to heating circular flow.Heat exchanger in winter (5) is made evaporimeter and is used near the air draft side, utilize the thermic load of air draft to improve evaporator temperature.So heat by improving evaporating temperature winter.The north is in the winter of cold, and abominable external environment condition allows a lot of off-premises stations be in holding state.And this unit is lower than under the design temperature in limited time monitoring environment temperature, and unit can move under specific state.Along with unit operation, intelligence control system monitoring wind pushing temperature reaches on the design temperature prescribes a time limit, and returns to normal operation mode again.Intelligence control system has solved not work problem of standby in winter, has prevented the northern area common phenomenon of blowing a cold wind in winter, has reduced heat exchanger frosting probability.This unit design should be as the first-selected product of northern area with the starting point of northern adverse circumstances as design.
This is gone back unit and also comprises the cyclelog of realizing Based Intelligent Control.Summer, compressor (1) started after 30 seconds at fan operation when freezing, and unit is when refrigeration and air vent mode conversion, and compressor has 180 seconds delay protection; During winter heating, when being higher than under the start-up temperature, environment temperature prescribes a time limit, the unit operation pattern is with freezing summer, prescribe a time limit when environment temperature is lower than under the design temperature, pressure sensor detects pressure at expulsion and is lower than when setting value, in order to prevent to blow a cold wind over and low pressure alarming, start frequency converter by cyclelog, pressure fan begins low-speed running, is higher than when setting value when pressure sensor detects pressure at expulsion, and pressure fan normally moves.
The utility model adopts advanced intelligence control system to solve not work problem of standby in winter, has prevented the northern area common phenomenon of blowing a cold wind in winter, has reduced heat exchanger frosting probability.By various Based Intelligent Control, pipeline optimization, make COP reach 3.5.
Above argumentation only is the preferred example of the utility model embodiment, is in order to explain and to illustrate, is not the restriction to utility model itself.The utility model is not limited to specific embodiment disclosed herein, and is determined by following claim.In addition, the record relevant with certain embodiments in the description in front can not be interpreted as the restriction to the definition of the term that uses in scope of the present utility model or the claim.Various other the different embodiment and the various distortion of disclosed embodiment it will be apparent to those skilled in the art that.But all these embodiment, change and distortion are all in the scope of claims.
