Description
Technical field
The utility model relates to a kind of air-conditioning unit, specifically dual-effect energy-saving type roof Top Air-conditioning Unit.
Background technology
Along with China's expanding economy, energy problem is day by day serious, and air-conditioning is the capital equipment that consumes the energy.In air-conditioning system in order to meet the requirement of the new wind such as malleation in room, personnel and health, air-conditioning system is generally all designed with very large resh air requirement and exhaust air rate, because the duty ratio of new wind is larger, need the refrigerating capacity of consumption larger, because the air of low temperature in room is directly discharged into atmosphere again, cause energy dissipation simultaneously.At present exhaust air energy recovery is also done to a large amount of research work both at home and abroad, but be all to adopt single a kind of recuperation of heat modes such as heat pipe, runner, plate-fin, just new wind has been done to a pretreatment, the energy of return air has not been had to fully effective recycling.Also have in air-conditioning system in order to meet humidity requirement, will reach required ventilation state point through heat (conventionally adopting electrical heating, hot water heating or Steam Heating) again by cooling air, have cold-hot counteraction phenomenon, this process has caused wasting of the energy.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, provide a kind of energy recovery efficiency high, unit equipment investment is low, and installation space is little, easy for installation, and has saved the dual-effect energy-saving type roof Top Air-conditioning Unit of the air energy that heat needs again.
For realizing above-mentioned utility model object, the technical solution adopted in the utility model is a kind of dual-effect energy-saving type roof Top Air-conditioning Unit, comprise connected successively compressor, condenser, liquid reservoir, device for drying and filtering, magnetic valve, heating power expansion valve and evaporimeter, and evaporimeter is connected with compressor.
Wherein, also comprise the first roughing efficiency air filter, runner heat reclamation device, board-like heat regenerator and pressure fan; And the first roughing efficiency air filter, runner heat reclamation device, evaporimeter, board-like heat regenerator and pressure fan set gradually along the new general mood flow path direction of new wind side.
Wherein, also comprise the second roughing efficiency air filter and exhaust blower, and described the second roughing efficiency air filter, board-like heat regenerator, runner heat reclamation device and exhaust blower are successively set on the air draft airflow direction of air draft side.
Wherein, the output of described compressor is connected with high-pressure manometer, and the input of compressor is connected with low pressure gauge.
Wherein, described compressor is also parallel with a pressure controller.
Wherein, a side of described condenser is also provided with axial flow blower.
The utility model is compared with common all-fresh air unit, and unit has increased runner heat reclamation device and board-like heat regenerator to be done pre-cold-peace to new wind and heat twice processing.Runner heat reclamation device carries out precooling treatment one time to new wind, reclaims the energy in air draft, and new wind enters the further cooling down of evaporimeter after the precooling of runner heat reclamation device.Cooled air again carries out heat exchange through board-like heat regenerator and return air and obtains heat again, and while return air obtains further cooling.Cooled air draft significantly improves pre-cooling of fresh air effect through runner heat reclamation device, has reduced new wind load, and unit integral energy organic efficiency is also improved.
Beneficial effect: compared with prior art, the utlity model has following advantage: the utility model had both met the requirement of new wind processing, take full advantage of again two kinds of energy recycle devices and reclaimed the energy of air draft, play effects of energy saving and emission reduction.The utility model can be applicable to multiple business or the civil buildings such as office building, high-end residential, meeting room, dining room, hospital; Large-scale unit can be used for the new wind pretreatment of central air-conditioning.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, the present embodiment is implemented under take technical solution of the present invention as prerequisite, should understand these embodiment and only be not used in and limit the scope of the invention for the present invention is described.
As shown in Figure 1, a kind of dual-effect energy-saving type roof Top Air-conditioning Unit, comprise connected successively compressor 1, condenser 2, liquid reservoir 3, device for drying and filtering 4, magnetic valve 5, heating power expansion valve 6 and evaporimeter 7, and evaporimeter 7 is connected with compressor 1, thereby forms an overall close loop.
Wherein, also comprise the first roughing efficiency air filter 8, runner heat reclamation device 9, board-like heat regenerator 10 and pressure fan 11; And the first roughing efficiency air filter 8, runner heat reclamation device 9, evaporimeter 7, board-like heat regenerator 10 and pressure fan 11 set gradually along the new general mood flow path direction of new wind side.
Wherein, also comprise the second roughing efficiency air filter 12 and exhaust blower 13, and described the second roughing efficiency air filter 12, board-like heat regenerator 10, runner heat reclamation device 9 and exhaust blower 13 are successively set on the air draft airflow direction of air draft side.
Wherein, the output of described compressor 1 is connected with high-pressure manometer 14, and the input of compressor 1 is connected with low pressure gauge 15.
Wherein, described compressor 1 is also parallel with a pressure controller 16.
Wherein, a side of described condenser 2 is also provided with axial flow blower 17.
Air-treatment unit structural design of the present utility model is for two-layer up and down, and wherein exhaust blower and pressure fan are placed on one deck above.Evaporimeter, the first roughing efficiency air filter and the second roughing efficiency air filter are placed on one deck below unit, and runner heat reclamation device and board-like heat regenerator are arranged in the middle of unit.
Running of the present utility model is divided into kind of refrigeration cycle and two processes of air-treatment.
Kind of refrigeration cycle: compressor is high temperature and high pressure gas by low-temperature low-pressure refrigerant gas compression, high temperature and high pressure gas out enters into condenser through high-pressure manometer from compressor.High temperature and high pressure gas enters into condenser and is cooled to high temperature high pressure liquid, high temperature high pressure liquid enters into liquid reservoir and then enters into evaporimeter through device for drying and filtering, magnetic valve and heating power expansion valve reducing pressure by regulating flow, heat absorption vaporization in evaporimeter, absorb airborne heat air is cooling simultaneously, again compressed by entering into compressor after low pressure gauge after cold-producing medium heat absorption vaporization.
Air handling process: outdoor new wind first by after the first roughing efficiency air filter after runner heat reclamation device absorbs the energy in air draft through pervaporation device cooling processing, again after board-like heat regenerator reclaims the energy in return air, send into air-conditioned room by pressure fan.The thermic load intensification of sending into the cold air absorption air-conditioned room of air-conditioned room enters return air channel afterwards and first enters into board-like heat regenerator through the second roughing efficiency air filter, self obtain cooling at the new wind of heating simultaneously, then enter runner heat reclamation device again cooling new wind absorb after heat in new wind by outside exhaust blower discharge chamber, thereby reach the object that reclaims cold in air draft.
In running, the pressure of the import and export cold-producing medium of pressure controller control compressor, within the high-low pressure of refrigeration system exceeds normal range of operation time, controls compressor and quits work.
