Detailed description of the invention
Further illustrate the detailed description of the invention of the energy-saving track train air-conditioning of the utility model band total-heat exchanger below in conjunction with accompanying drawing, but it is noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1 and 2.With an energy-saving track train air-conditioning for total-heat exchanger, Stainless Steel Shell 1 arranges evaporation fan 2, evaporator 3, total-heat exchanger 6, useless exhaust fan 8, compressor 9, condenser 10 and condensation fan 11 and corresponding cooling piece pipe line parts and electric fittings: evaporation fan 2 and evaporator 3 and associated pipe are set in the front end of Stainless Steel Shell 1; Condenser 10 and condensation fan 11 and associated pipe are set in the rear end of Stainless Steel Shell 1; Compressor 9, total-heat exchanger 6 and useless exhaust fan 8 and associated pipe are set in the centre of Stainless Steel Shell 1; The refrigeration system of whole air-conditioning is divided into two cover systems, and the Total heat exchange of new wind and useless air draft is also divided into two to overlap independently system, is separately positioned on the left and right sides (direction for shown in the structure in Fig. 1) of Stainless Steel Shell 1.
The feature of track train air-conditioning of the present utility model is provided with total-heat exchanger 6 and useless exhaust fan 8.Below mainly introduce the structure of total-heat exchanger 6 and useless exhaust fan 8 and setting thereof and annexation, the installation of air-conditioning miscellaneous part is substantially with existing track train air conditioner structure.
Described total-heat exchanger 6 is box-shaped structural member, is arranged in the Stainless Steel Shell 1 between described evaporator 3 and described compressor 9.At total-heat exchanger 6 box house, interchange of heat movement, useless exhaust fan 8 are installed, at total-heat exchanger 6 casing outer setting new wind ventilation inlet 4, new wind exhaust outlet 7, useless air draft import 12 and useless wind exhausting outlet 14: described new wind ventilation inlet 4 is connected with new wind air channel 5 by circular flange; Described new wind exhaust outlet 7 is mixed with return air by a static pressure chamber; Described useless air draft import 12 is arranged on the bottom of described total-heat exchanger 6, by it useless exhaust outlet with air-conditioning by being tightly connected.Useless air draft enters after total-heat exchanger 6 exchanges by described useless air draft import 12, enters air by centrifugal useless exhaust fan 8 dorsad.The lower end of total-heat exchanger 6 is socketed on former return air inlet for air-conditioner.Originally the useless exhaust outlet be arranged on guideway vehicle is moved to air-conditioning inside by the utility model, by return air inlet for air-conditioner being divided into return air inlet for air-conditioner 13 and useless air draft import 12, both, the lower end of described total-heat exchanger 6 was provided with return air inlet for air-conditioner 13 and useless air draft import 12: described useless air draft import 12 be connected by crimping filler rod and the air-conditioning exhaust outlet that originally gave up.
New wind air channel 5 is set at the outside front ends of described total-heat exchanger 6 and by described new wind air channel 5, described total-heat exchanger 6 is connected with the new wind ventilation inlet 4 of air-conditioning.Useless exhaust fan 8 is installed in rear end outside described total-heat exchanger 6, and described useless exhaust fan 8 can adopt centrifugal exhaust fan dorsad.The inner side that total-heat exchanger 6 arranges total-heat exchanger 6 described in a useless exhaust fan 8(is the junction of two cover total-heat exchangers 6).The upper end of described useless exhaust fan 8 is set to useless wind exhausting outlet 14(see Fig. 2).
The new wind exhaust outlet 7 of venetian blind type is set in the upper end of described total-heat exchanger 6.
The useless air draft of low temperature enters total-heat exchanger 6 from useless air draft import 12, the new general mood body of high temperature enters total-heat exchanger 6 from new wind ventilation inlet 4, after the useless air draft of low temperature and the new general mood body of high temperature carry out sufficient thermal exchange by adverse current in described total-heat exchanger 6, useless air draft enters in air by the exhaust fan 8 that gives up through useless wind exhausting outlet 14; And the new wind after heat-shift continues to mix with a part of return air entered from return air inlet for air-conditioner 13, then sucked by evaporation fan 2, then enter after evaporator 3 cools and send into rail train carriage again.
The working process of the energy-saving track train air-conditioning of the utility model band total-heat exchanger is:
Evaporation fan 2 is sucked air by useless air draft import 12 and mixes with the new wind gathered by new wind ventilation inlet 4 from total-heat exchanger 6 in rail train carriage, then enters evaporator 3 and carries out heat exchange, then send into rail train carriage.In the process, refrigerant in evaporator 3 is gasified because of heat absorption by liquid state, sucked by compressor 9, the gas of High Temperature High Pressure is become after overdraft, enter condenser 10 to be again condensed the Air flow that blower fan 11 sucks from air, thus become the liquid of high pressure low temperature, again enter in evaporator 3 after eventually passing expansion valve throttling, thus form the energy exchange circulation of once refrigeration and gas.
Original return air inlet for air-conditioner is divided into return air inlet for air-conditioner 13 and useless air draft import 12 by the utility model, the air-conditioning return air of total-heat exchanger 6 side is allowed to be connected with useless air draft import 12, and be sent to the new wind carrying out with return air in rail train carriage mixing and enter from the outside of total-heat exchanger 6, by the exchange of total-heat exchanger 6, the exchange of cold is carried out in the new general mood body of high temperature and the useless air draft of low temperature, thus the cold reclaimed in useless air draft, reduce the load of evaporator 3, reach the recycling of cold and energy-conservation effect.
