Description

A kind of dual-effect energy-saving type roof Top Air-conditioning Unit
Technical field
The present invention relates to a kind of air-conditioner set, specifically dual-effect energy-saving type roof Top Air-conditioning Unit.
Background technology
With China's expanding economy, energy problem's getting worse, and air-conditioning is the capital equipment for consuming the energy.In sky In order to meet the requirement of the fresh airs such as malleation in room, personnel and health in adjusting system, air-conditioning system is generally designed very big Resh air requirement and exhaust air rate, because the load of fresh air is bigger, it is necessary to which the refrigerating capacity of consumption is bigger, simultaneously because low temperature in room Air again be directly discharged to air, cause energy dissipation.Exhaust air energy recovery have also been made both at home and abroad at present and largely grind Study carefully work, but be all using a kind of single recuperation of heat modes such as heat pipe, runner, plate-fins, simply fresh air is done once pre- Processing, does not have fully effective recycling to the energy of return air.Also in order to meet humidity requirement in air-conditioning system, by air Cooling will pass through reheating(Generally use electrical heating, hot water heating or steam heating)Reach required ventilation state point, exist Cold-hot counteraction phenomenon, this process cause wasting for the energy.
The content of the invention
The purpose of the present invention is in view of the deficienciess of the prior art, providing a kind of energy recovery efficiency height, unit equipment Invest low, installation space is small, easy for installation, and saves the dual-effect energy-saving type roof type of the energy of air reheating needs Air-conditioner set.
For achieving the above object, the technical solution adopted by the present invention is a kind of dual-effect energy-saving type roof type air-conditioner Group, including compressor, condenser, liquid reservoir, device for drying and filtering, magnetic valve, heating power expansion valve and the evaporator being sequentially connected, and Evaporator is connected with compressor again.
Wherein, in addition to the first roughing efficiency air filter, runner heat reclamation device, board-like heat regenerator and pressure fan;And first The fresh air airflow direction of roughing efficiency air filter, runner heat reclamation device, evaporator, board-like heat regenerator and pressure fan along fresh air side Set gradually.
Wherein, in addition to the second roughing efficiency air filter and exhaust blower, and 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 end of the compressor is connected with high-pressure manometer, and the input of compressor is connected with low pressure Table.
Wherein, the compressor is also parallel with a pressure controller.
Wherein, the side of the condenser is additionally provided with axial flow blower.
It is of the invention compared with common all-fresh air unit, unit adds runner heat reclamation device and board-like heat regenerator pair Fresh air does precooling and heating is handled twice.Runner heat reclamation device carries out a precooling treatment to fresh air, reclaims the energy in air draft Amount, fresh air enter the further cooling down of evaporator after runner heat reclamation device precooling.Air after cooling again passes by plate Formula heat regenerator carries out heat exchange with return air and obtains reheating, while return air is further cooled down.Air draft after cooling is by turning Take turns heat reclamation device to improve pre-cooling of fresh air significant effect, reduce new wind load, unit integral energy organic efficiency also obtains Improve.
Beneficial effect:Compared with prior art, the present invention has advantages below:The present invention had both met wanting for Fresh air handing Ask, take full advantage of the energy that two kinds of energy recycle devices have reclaimed air draft again, play effects of energy saving and emission reduction.The present invention can apply In a variety of business such as office building, high-end residential, meeting room, dining room, hospital or civil buildings;Large-scale machine set can be used for central air-conditioning Fresh air pretreatment.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, and the present embodiment is with technical solution of the present invention Premised under implemented, it should be understood that these embodiments are only illustrative of the invention and is not intended to limit the scope of the invention.
As shown in figure 1, a kind of dual-effect energy-saving type roof Top Air-conditioning Unit, including be sequentially connected compressor 1, condenser 2, Liquid reservoir 3, device for drying and filtering 4, magnetic valve 5, heating power expansion valve 6 and evaporator 7, and evaporator 7 is connected with compressor 1, from And form the close loop of an entirety.
Wherein, in addition to the first roughing efficiency air filter 8, runner heat reclamation device 9, board-like heat regenerator 10 and pressure fan 11; And first roughing efficiency air filter 8, runner heat reclamation device 9, evaporator 7, board-like heat regenerator 10 and pressure fan 11 are along fresh air side Fresh air airflow direction set gradually.
Wherein, in addition to the second roughing efficiency air filter 12 and exhaust blower 13, and second roughing efficiency air filter 12, board-like heat are returned Device 10, runner heat reclamation device 9 and exhaust blower 13 is received to be successively set on the air draft airflow direction of air draft side.
Wherein, the output end of the compressor 1 is connected with high-pressure manometer 14, and the input of compressor 1 is connected with low pressure Pressure gauge 15.
Wherein, the compressor 1 is also parallel with a pressure controller 16.
Wherein, the side of the condenser 2 is additionally provided with axial flow blower 17.
The air-treatment unit structure design of the present invention is upper and lower two layers, and wherein exhaust blower and pressure fan is placed on above one Layer.Evaporator, the first roughing efficiency air filter and the second roughing efficiency air filter are placed on below unit one layer, runner heat reclamation device and Board-like heat regenerator is arranged among unit.
The running of the present invention is divided into two processes of kind of refrigeration cycle and air-treatment.
Kind of refrigeration cycle:Low-temperature low-pressure refrigerant gas compression is high temperature and high pressure gas by compressor, high temperature and high pressure gas from Compressor out enters condenser by high-pressure manometer.High temperature and high pressure gas enter condenser and are cooled to high-temperature high-pressure liquid Body, high temperature high pressure liquid enter liquid reservoir and then entered by device for drying and filtering, magnetic valve and heating power expansion valve reducing pressure by regulating flow To evaporator, vaporization of being absorbed heat in evaporator, while the heat in absorption air cools down air, leads to after refrigerant heat absorption vaporization Cross after low pressure gauge and enter compressor and compressed again.
Air handling process:Outdoor fresh air is arranged by being absorbed after the first roughing efficiency air filter by runner heat reclamation device first Through pervaporation device cooling treatment after energy in wind, again pass by after the energy in board-like heat regenerator recovery return air by pressure fan It is sent into air-conditioned room.It is sent into after the thermic load heating of the cold air absorption air-conditioned room of air-conditioned room into return air channel first Entered by the second roughing efficiency air filter in board-like heat regenerator, heating fresh air simultaneously itself cooled down, subsequently into turn Wheel heat reclamation device cools down the heat that fresh air is absorbed in fresh air and discharges outdoor by exhaust blower afterwards again, so as to reach recovery air draft The purpose of middle cold.
In the process of running, the pressure of the inlet and outlet refrigerant of pressure controller control compressor, when the height of refrigeration system When low pressure is in normal operation range, control compressor is stopped.
