多联机空调系统以其节能高效、安装维修简单、适用性广以及控制灵活方便等优点受到了广泛的欢迎。随着工程量的增大和应用范围的不断扩展，在高层建筑中的应用也日趋广泛。该系统所使用的室外机为风冷热泵型的，风冷热泵机组以空气作为冷热源，由于空气的比热容小以及室外侧蒸发器的传热温差小等原因，故所需风量较大，因而环境空气应保持流畅，不受阻碍，并且不形成回流。否则将影响热泵型机组的排热与吸热，进而降低机组效率，严重时甚至会使机组因高压或低压保护动作而停机，其中又以夏季冷凝器的高压保护问题更为严重。

Air conditioning system with its energy saving and high efifciency, simple installation and repair, wide applicability and advantages of lfexible and convenient control have been widely welcomed. With the engineering quantity increasing and the expansion of the scope of application, the application in the high-rise building is becoming more and more widely. The outdoor machine are used in this system for the air cooled heat pump, air-cooled heat pump unit with air as cold and heat sources, because the air speciifc heat capacity and the heat transfer temperature outdoor evaporator is smaller, the required air volume is larger, so the air environment should be kept smooth, unimpeded, and does not form the relfux. Otherwise it will affect the heat and the heat absorption heat pump unit discharge, thereby reducing the efifciency of the unit, and even make the unit shut down due to high or low voltage protection action, and the problem of high pressure protection of the condenser is more serious in summer.
