Example Embodiment

[0076] The present invention will be described in detail below with reference to the drawings and embodiments.

[0077] Figure 6 Is a schematic diagram of the connection relationship of the present invention; Figure 7 It is a schematic diagram of the structure of the present invention and the flow of refrigerant.

[0078] As shown in the figure, the outdoor unit 100 is composed of a constant speed compressor 120, an inverter compressor 120', a liquid storage tank 132, an outdoor heat exchanger 180, and an outdoor solenoid valve 102 (LEV: linear expansion valve). The indoor unit 200 is composed of an indoor heat exchanger 202 and an expansion valve 204.

[0079] In a one-to-multiple air conditioner, a plurality of indoor units 200 are connected to one or more than two outdoor units 100. A single common liquid pipe 210 in which a liquid refrigerant flows and a single common pipe 212 in which a gas refrigerant flows are provided in communication between the outdoor unit 100 and th...

Abstract

The present invention discloses multi-split air conditioner with compressor with several evaporation loops. The multi-split air conditioner includes one or more outdoor unit with compressor, liquid storage, outdoor heat exchanger and outdoor solenoid valve; several indoor units with indoor heat exchanger, expansion valve, branched gas pipe and branched liquid pipe; single common liquid pipe set between the outdoor unit and indoor units for liquid refrigerant to flow through; single common gas pipe set between the outdoor unit and indoor units for gas refrigerant to flow through; and high and low pressure common pipe set between compressors of different outdoor units for homogenizing refrigerant. The present invention has less pipes, simple operation, facilitated installation of the system, high overall heat exchange efficiency and other advantages.

Description

technical field [0001] The invention relates to a compression device with several evaporation circuits. More specifically, at least one outdoor unit is connected to multiple indoor units through a single pipe, and two or more indoor units are connected to form a multi-air conditioner with high and low pressure common pipes. Background technique [0002] Generally speaking, an air conditioner is a kind of refrigeration and heating equipment, and its basic principle is as follows: the hot air sucked into the room exchanges heat with the low-temperature refrigerant. Then, the air after heat exchange is exhausted into the room again. By repeating the above process, a cooling operation is performed; or by a reverse process to the above, a heating operation is performed. An air conditioner is composed of a compressor, a condenser, an expansion valve, and an evaporator, forming a series of cyclic machines. [0003] In recent years, in addition to the above-mentioned cooling and ...
