Description

An air guide device for layered arrangement of multi-connected outdoor units

technical field

The utility model belongs to the technical field of multi-connected air-conditioning systems, and specifically relates to an air guide device for layered arrangement of multi-connected outdoor units. Operational efficiency of on-line air conditioning systems.

Background technique

With the increasing requirements for building energy conservation, the multi-split air-conditioning system has been widely used in various types of commercial buildings, hotels and other projects with many small independent spaces because of its good energy-saving effect. And this type of commercial buildings and hotels usually have a fashionable and novel appearance, and the exterior design cannot be easily changed. In order to ensure the decorative effect of the facade of the building, the multi-connected outdoor unit is usually installed indoors.

The most basic requirement for the working environment of the multi-connected outdoor unit is that there is no air short circuit in the system, that is, the air intake is smooth and uninterrupted, and the exhaust air is smooth without backflow. Therefore, in order to ensure the normal use of the outdoor unit, the multi-connected outdoor unit is usually arranged On roofs or air-conditioned rooms.

The outdoor unit is arranged on the roof. The advantage is that the roof is relatively open, the exhaust air is smooth, and the hot air is quickly dissipated to the high altitude; the disadvantage is that when many outdoor units are arranged on the same roof, the air intake is tortuous and interferes a lot. The disadvantages of long refrigerant pipeline and high cost. If the outdoor unit is arranged in the air-conditioning equipment room. The advantage is that the refrigerant pipeline is short and the equipment is concealed; the disadvantage is that there may be poor air intake and exhaust and backflow. Especially when several outdoor units are vertically arranged in layers on different floors, it is easy to cause the exhaust air of an outdoor unit on a certain floor to be inhaled by the outdoor units on the upper or lower floor as air intake, affecting the overall performance of the equipment, resulting in a decrease in equipment capacity and increasing energy consumption.

Chinese patent 201320051156.3 discloses a new type of multi-line layered arrangement device, which includes an air-conditioning outdoor unit installed on each floor. Air inlets are provided on both sides and the front of the outdoor unit. There is an exhaust shaft, and the top of the outdoor unit is connected to the air outlet on the outer facade of each floor wall through the air guide tube, and the air outlet is connected to the exhaust shaft; the air inlet is provided There are air intake louvers. The air in and out of the multi-line is separated, which effectively improves the heat dissipation efficiency of the multi-line, thereby improving the cooling efficiency of the multi-line. But it can only be used for air discharge in the cooling season, and convection will still occur due to the discharge of hot air in the heating season.

Utility model content

The purpose of this utility model is to provide a method that prevents the air inlet and outlet of the outdoor unit from mixing and facilitates the short circuit of the outdoor unit when the upper and lower floors are placed in the air conditioner room. The air guide device for the centralized discharge of the air from the outdoor unit can also be integrated with the exterior design of the building in the design of new buildings. The whole device collects the exhaust air of the multi-unit outdoor unit in a unified manner, and discharges it in a concentrated manner, so that the airflow organization of the multi-unit air inlet and outlet air can be effectively separated, which is conducive to improving the operating efficiency of the multi-unit system.

Technical solutions

In order to achieve the above technical purpose, the utility model designs an air guide device for layered arrangement of multi-connected outdoor units, including multi-connected outdoor units arranged on each floor, floor air guide pipes and air guide pipes arranged on the wall of the air-conditioning equipment room The exhaust shaft on the outside of the facade, the multi-connected outdoor unit is installed in the air-conditioning equipment room, and it is characterized in that: the top exhaust port of the multi-connected outdoor unit is vertically connected with the wall outside the air-conditioning equipment room through the floor air guide pipe. The exhaust shafts on the surface are connected; the front or/and side of the multi-connected outdoor unit corresponds to the wall elevation of the air-conditioning equipment room, and the right grille air inlet is provided.

The bottom of the exhaust shaft is provided with a winter shaft air outlet, and the top is respectively provided with a summer shaft air outlet.

Further, several multi-connected outdoor units can be placed side by side in the air-conditioning equipment room.

Further, the winter shaft air outlet and the summer shaft air outlet can be opened simultaneously or separately.

Beneficial effect

The utility model provides an air guide device that is beneficial to the layered arrangement of multi-connected outdoor units, which separates the air inlet and outlet of the multi-connected units placed in the air-conditioning equipment room, avoids the short-circuit phenomenon of the air inlet and outlet, and effectively improves the multi-connection system. On-line heat exchange effect; the temperature of the multi-line air inlet is reduced in summer, and the temperature of the multi-line air inlet is increased in winter to prolong the service life of the multi-line; at the same time, when building a new building, the design of the exhaust shaft can be considered in terms of architectural beauty and practicality. Combined with the building as a whole, the space position of the shaft is reserved during the construction of the building to reduce the impact on the building's facade.
