Heat exchange system of multi-connected air conditioner and air conditioner

Abstract

The present invention proposes a heat exchange system of a multi-connected air conditioner and the air conditioner, wherein the heat exchange system of the multi-connected air conditioner includes an outdoor unit component and an indoor unit component, the indoor unit component includes a fan coil unit, and the fan coil unit has a water inlet There are multiple fan coil units connected in parallel; the outdoor unit components include water inlet pipes and water outlet pipes, and the water inlet pipes are connected to the water outlets of the fan coil units so as to input the water output from the fan coil units. to the inside of the outdoor unit for heat exchange, and the outlet pipe is connected to the water inlet of the fan coil unit to transport the water after heat exchange of the outdoor unit to the inside of the fan coil unit; the indoor unit component also includes a wire controller, and the outdoor unit component also includes a It includes a control unit, which is connected with the wire controller, so as to transmit the parameters for controlling the operation of the fan coil unit to the wire controller; the air conditioner includes the heat exchange system of the above-mentioned multi-connected air conditioner. The invention can shorten the product development period and reduce the cost.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a heat exchange system of a multi-connected air conditioner and the air conditioner. Background technique [0002] Multi-connected air conditioners are commonly known as "one-to-many", which means that one outdoor unit is connected to two or more indoor units through piping. The outdoor side adopts air-cooled or water-cooled heat exchange form, and the indoor side adopts direct evaporation heat exchange Air Conditioning System. The multi-connection system has the advantages of being able to realize the communication between the indoor unit and the outdoor unit, regional control, flexible use, and obvious energy saving when it is partially matched. It is currently widely used in small and medium-sized buildings and some public buildings. [0003] However, the air conditioners using the multi-connection system currently have obvious disadvantages: due to the n...

Problems solved by technology

[0003] However, the air conditioners using the multi-connection system currently have obvious disadvantages: due to the need to install multiple indoor units of different types, the connection methods of indoor and outdoor units are different, so on the one hand, the product development cycle is long, and long and short piping, height differences, etc. are required Reliability testing generally takes at least 10 months for a new system, and changes in the form of indoor units will affect the reliability of the whole system, and the verification workload is heavy. On the other hand, outdoor units and indoor units are fixed collocations. Indoor units need to be purchased from multi-split manufacturers, the cost is too high
