Description

Air-conditioning unit for elevator cabs

Technical field:

The utility model relates to a kind of air-conditioning unit for elevator cabs.

Background technology:

Be used in the elevator cab at present ventilating and thermoregulator equipment all is employing minitype air conditioners or directly adopting blower fan to blow reaches.And these two kinds of existing problems of equipment are more relatively.Such as: minitype air conditioner must make the temperature of gas descend under the refrigeration of liquefied ammonia by the gas that produces after the work done of compressor compresses gas, have again under the effect of blower fan of inside, bridge railway carriage or compartment wind is sent into the inner refrigeration of elevator, this equipment energy consumption is big, noise is big, the volume main point is divided two parts work, manufacturing cost is high, inconvenience is installed, its refrigerant fluid is that ammonia is revealed easily, can influence cooling effect after long-time the use, contaminated air, compressor want periodic maintenance and inconvenience and can produce the miscellaneous part that water droplet can have influence on elevator, make air become dry simultaneously, influence humidity.Adopt blower ventilation, though this equipment cost is low, but can't to the temperature of air regulate and also noise big.It is exactly that these two kinds of equipment all can only be used for refrigeration and ventilation under the limited situation of manufacturing cost that in use all there is a same deficiency in above two kinds of equipment of while, can't reach the effect of heating.Can't realize the effect of both cooling and heating, just can't use, cause and the big wasting of resources in winter.

Summary of the invention:

The purpose of this utility model provides a kind of air-conditioning unit for elevator cabs, and this device not only helps the adjusting of elevator cab cold and heat air, and simple in structure, low cost of manufacture, and result of use is good.

The purpose of this utility model is achieved in that this air-conditioning unit for elevator cabs, comprise casing, described casing middle part is provided with the semiconductor chilling plate that casing is isolated into cold air duct and hot-air channel, the refrigeration end of described semiconductor chilling plate is towards the cold air duct side, heat end towards the hot-air channel side, the two ends of described semiconductor chilling plate cold air duct are respectively equipped with can be toward the axial flow blower A of the outer exhausting of casing, B, the two ends of described semiconductor chilling plate hot-air channel also are provided with can be toward the axial flow blower C of the outer exhausting of casing, D, described axial flow blower A, C is connected with two air-flow ports of elevator cab respectively.

Distinguishing feature of the present utility model is in the application aspect the elevator cab air conditioning by semiconductor chilling plate, and in conjunction with the control on the setting of axial flow motor installation position and break-make opportunity, the flexible modulation of cold and heat air in the elevator cab has made full use of existing resource when having realized Various Seasonal.

In addition, this apparatus structure is simple, and low cost of manufacture is easy for installation, has broad prospect for its application.

The specific embodiment:

Air-conditioning unit for elevator cabs of the present utility model, comprise casing 1, described casing 1 middle part is provided with the semiconductor chilling plate 4 that casing 1 is isolated into cold air duct 2 and hot-air channel 3, the refrigeration end 5 of described semiconductor chilling plate 4 is towards cold air duct 2 sides, heat end 6 towards hot-air channel 3 sides, the two ends of described semiconductor chilling plate 4 cold air ducts 2 are respectively equipped with can be toward the axial flow blower A of casing 1 outer exhausting, B, the two ends of described semiconductor chilling plate 4 hot-air channels 3 also are provided with can be toward the axial flow blower C of casing 1 outer exhausting, D, described axial flow blower A, C is connected with two air-flow ports 8 of elevator cab 7 respectively.

In order to strengthen heat-conducting area, strengthen the effect of heat exchange, the refrigeration end 5 of above-mentioned semiconductor chilling plate 1 holds 6 to be respectively equipped with the fin 9 that is used for conduction cooling and heat conduction with heating.

Said machine casing 1 side is provided with natural wind air inlet 10.

In order to control opportunity to the power supply of semiconductor chilling plate and axial flow motor and to the break-make of axial flow motor, this device also is provided with power circuit 11 and circuit for controlling motor 12.

Above-mentioned circuit for controlling motor 12 comprises axial flow blower A, B, C, D, K switch 1, K switch 2, adjustable resistance 13 and connection line 14, described machine operation circuit 12 by refrigeration machine operation branch road 15 with heat 16 parallel connections of machine operation branch road after adjustable resistance 13 is connected with power circuit 11, the K switch 1 that described refrigeration machine operation branch road 15 is serially connected with axial flow blower A, D and is used to control A, D break-make describedly heats the K switch 2 that machine operation branch road 16 is serially connected with axial flow blower B, C and is used to control B, C break-make.

During the refrigeration work state, at first it is started working for semiconductor chilling plate 4 power supplies by power circuit 11, cut-off switch K2 then, Closing Switch K1, this moment, fresh air entered cold air duct 2 by the natural wind air inlet, through with the heat exchange of the refrigeration end 5 of semiconductor chilling plate 4 after, A pumps cold wind in elevator cab 7 by the axial flow motor, thus the axial flow motor D is then pumped the hot blast formation cooling air system for the distribution of commodities to elevator cab 7 outside.

During the heating duty, at first it is started working for semiconductor chilling plate 4 power supplies by power circuit 11, cut-off switch K1 then, Closing Switch K2, this moment, fresh air entered hot-air channel 3 by the natural wind air inlet, through with semiconductor chilling plate 4 heat end 6 heat exchange after, C pumps hot blast in elevator cab 7 by the axial flow motor, forms the air flow system that heats thereby axial flow motor B then pumps cold wind to elevator cab 7 outside.
