Description

Low-noise compact type integral elevator air conditioner Technical Field The invention relates to the technical field of air conditioning equipment, in particular to a low-noise compact integral elevator air conditioner. Background Elevators are increasingly gaining importance as critical vertical vehicles in modern high-rise buildings for the comfort of their riding environment. In the elevator operation process, the problems of temperature rise, humidity increase, unsmooth air circulation and the like easily occur due to the reasons of intensive personnel, equipment heating, relative sealing of a hoistway and the like in the elevator, and passengers easily produce smoldering and uncomfortable feeling especially in seasons with hot weather or under the working condition of poor ventilation. For this reason, the addition of a dedicated air conditioning system in an elevator car has become an important technical direction for improving riding experience and improving equipment quality. Among various elevator air conditioners, the integral air conditioner gradually becomes the main stream of the market due to the characteristics of high structural integration level, no need of a machine room, relatively simple and convenient installation and maintenance and the like. Such devices typically integrate the core components of the compressor, condenser, evaporator, fan, etc. into a closed housing and mount directly on top of the car. However, the common integral elevator air conditioner still has a plurality of common technical problems to be solved in practical use, namely, firstly, an axial flow fan or a centrifugal fan is generally adopted in consideration of heat exchange efficiency, the working speed is high, the air flow disturbance is large, the running noise is obvious, the mute comfort in the elevator car is directly influenced, secondly, the integral elevator air conditioner is limited by an installation space, a condenser is mostly in a pure air cooling heat dissipation mode, the heat dissipation efficiency is insufficient under a high-temperature working condition, the condensation pressure is easily caused to rise, the power consumption of the compressor is increased, the energy efficiency of the system is lower, furthermore, the traditional layout is mostly in a horizontal side-by-side structure, or the air supply of a large air pipe is still relied on after the integral elevator air conditioner is vertically stacked, the horizontal projection area of equipment is large, the limited installation and maintenance space at the top of the elevator car is seriously occupied, the difficulty is brought to the arrangement and daily maintenance of other equipment such as illumination, ventilation and the like, in addition, the condensed water generated in the refrigerating process is usually not utilized and is directly discharged, the water resource is wasted, and the energy saving potential of utilizing the latent heat of the evaporation heat for assisting the heat dissipation is missed. Related patent solutions have attempted to improve upon the above-described problems in the prior art. For example, chinese patent publication No. CN115638480a discloses a compact elevator air conditioner that realizes a compact layout between components by designing one side of a centrifugal fan impeller as a concave structure. Meanwhile, the whole device is in a transverse penetrating layout, the length direction size is still larger, an effective condensate water recycling and utilizing system is not arranged, and the condensate water discharging problem still exists. For another example, chinese patent publication No. CN120720663a proposes a vertical elevator air conditioner, in which an evaporator and a condenser are arranged in a vertically stacked manner, so as to reduce the floor area of the equipment. However, the proposal still uses the connection mode of the centrifugal fan and the large air pipe with the side air outlet, the running noise is not reduced, the large air pipe also continuously occupies the top space, and the compacting effect is limited. In summary, although the existing integral elevator air conditioner is mature in terms of function integration, the integral elevator air conditioner still has obvious defects in terms of low-noise operation, compact structure, efficient heat dissipation, condensate water recycling utilization and the like, and is difficult to simultaneously meet the comprehensive performance requirements of modern elevators on silence comfort, space saving, energy saving, high efficiency and convenience in maintenance. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the invention provides the low-noise compact integral elevator air conditioner, which realizes low-noise operation, compact installation and high-energy-efficiency refrigeration through the innovative structural layout, fan selecti
