Elevator air conditioner adopting semiconductor refrigeration technology

Abstract

The invention provides an elevator air conditioner adopting a semiconductor refrigeration technology. The elevator air conditioner comprises a machine case, a semiconductor refrigeration device, a cross-flow fan, an air quality detection module, a negative ion purification module, a water-free module and a control module. The air quality detection module and the negative ion purification module are arranged inside the machine case. The machine case comprises air inlets, first openings and a machine cabinet. The machine cabinet comprises an air outlet. The air inlets and the first openings communicate with the air outlet. The air inlets are located at the upper end of the machine case. The machine cabinet is located at the lower end of the machine case. The first openings are located between the air inlet and the machine cabinet. The first openings are arranged on the two sides of the machine case in the manner of being symmetrical about the air inlets. The machine cabinet is arranged on one side of the machine case. The semiconductor refrigeration device is installed on the first openings. The cross-flow fan is installed on the machine cabinet. The water-free module is installed onone side of the lower end of the machine case. With the elevator air conditioner adopting the semiconductor refrigeration technology, the quality of air in an elevator is greatly improved, the concentration of bacteria in the air is reduced, and condensate water is atomized through the water-free module.

Description

technical field [0001] The invention relates to an elevator air conditioner, in particular to an elevator air conditioner using semiconductor refrigeration technology. Background technique [0002] At present, most of the elevator air conditioners on the market still use R22 refrigerant for refrigeration, which will cause certain pollution to the environment, and the refrigerant will leak out. The noise during the operation of the air conditioner is relatively large, and the volume of the elevator air conditioner is relatively large. The installation area is large, which is not convenient for installation and maintenance and increases the load of the elevator car. [0003] In the application document with the Chinese application number 201910384760.X and the publication date of 2019.10.11, a semiconductor refrigeration elevator car air conditioning system is disclosed. The air conditioning system includes a refrigeration unit arranged on the upper side of the car body. The ...

[0004] But this air-conditioning system only dissipates heat to the first semiconductor assembly through the radiator, which only reduces the working temperature of the semiconductor refrigeration sheet through simple heat exchange; The air quality of the elevator car; the air is not filtered and purified, and is directly introduced into the elevator car, which easily causes discomfort in breathing in the elevator car; at the same time, the air conditioning system does not treat the condensed water formed during the refrigeration process; The air conditioning system is installed above the elevator car; in this way, the condensed water will drip into the elevator car, which will affect the experience of taking the elevator; at the same time, the condensed water will easily cause slippage, which has safety problems
