The heat preservation drainage device (2) comprises an upper heat preservation member (21) and a water pan (22); the water pan (22) is located below the upper heat preservation member (21) and connected to the upper heat preservation member (21), and divides an inner cavity of the housing (1) into a first cavity and a second cavity which are independent; the fan system (4) is fixedly mounted in the first cavity; and the heat exchange system (3) is fixedly installed in the second cavity and located between the upper heat preservation member (21) and the water pan (22). The housing (1) comprises a box body with a downward opening, and the box body comprises a bottom plate (11). An assembly method for the duct-type air conditioner comprises: placing the box body with the opening facing upwards; installing the upper heat preservation member (21) on the bottom plate (11); installing the heat exchange system (3) above the upper heat preservation member (21); installing the water pan (22) above the heat exchange system (3) to be connected to the upper heat preservation member (21); and fixedly installing the fan system (4) in the first cavity. The number of parts is reduced, and so the number of screws to be used is reduced, such that the assembly efficiency is improved.

摘要： A heat recovery variable-frequency multi-split heat pump system and a control method thereof. The system comprises an outdoor unit and at least two indoor units. The system is a three-pipe heating recovery multi-split heat pump system designed on the basis of a four-way reversing valve, and one indoor unit thereof is provided with two electronic expansion valves and two heat exchangers so that any indoor unit in the system can operate independently under three working conditions of refrigeration, heating or heat recovery dehumidification. Under multi-split condition, the system can operate under six working conditions, namely, the full-refrigeration working condition, the full-heating working condition, the common-heat-recovery working condition, the common-heat-recovery-dehumidification working condition, the heat recovery dehumidification-refrigeration-combination working condition and the heat recovery dehumidification-heating-combination working condition. Under the heat recovery dehumidification condition, a lower outlet air temperature, during low-temperature dehumidification, is raised by means of heat removal of a condenser so as to achieve the purpose of dehumidification without temperature fall or temperature rise, so that the thermal comfort and efficiency of the system are improved, and the refrigerating capacity and heating capacity of the system are effectively improved.
