A set for assembling a heat source unit of an air conditioner at the site of the air conditioner, includes a heat source heat exchanger module having a first casing, a heat source heat exchanger and a compressor module port fluidly communicated with the heat source heat exchanger, a compressor module having a second casing separate from the first casing, a compressor and a heat source heat exchanger module port fluidly communicated with the compressor, wherein the heat source heat exchanger module and the compressor module are fluidly communicatable via the compressor module port and the heat source heat exchanger port, a main board comprising a control logic of the air conditioner and a first electric connector, wherein at least one of heat source heat exchanger and compressor modules has a circuit board comprising a second electric connector, the circuit board of such a module being configured for data communication with the main board upon electrical connection of the circuit board and the main board via the first and second connectors. Further, a method for assembling a heat source unit of an air conditioner at the site of the air conditioner uses such a set.

Set and method for assembling a heat source unit

Air conditioner for conditioning a space inside a building includes a heat source unit and at least one indoor unit. The heat source unit has a heat exchanger unit and a compressor unit. The heat exchanger unit includes a first heat exchanger disposed in a first casing and configured to exchange heat with a heat source. The compressor unit includes a compressor disposed in a second casing separate from the first casing, the heat exchanger unit and the compressor unit being fluidly connected via a first liquid refrigerant pipe and a first gaseous refrigerant pipe. At least one indoor unit has a second heat exchanger configured to exchange heat with the space to be conditioned and being fluidly communicated to the heat exchanger unit and/or the compressor unit via a second liquid refrigerant pipe and a second gaseous refrigerant pipe. The outer diameter of the first liquid refrigerant pipe is larger than the outer diameter of the second liquid refrigerant pipe and/or the outer diameter of the first gaseous refrigerant pipe is larger than the outer diameter of the second gaseous refrigerant pipe.
