Water source multi-connected air conditioning system

Abstract

The invention discloses a water source multi-split air conditioning system which comprises an outdoor unit refrigerant system unit, an indoor unit, a water source cooling unit, a refrigerant and water side heat exchange unit and a compressor frequency conversion module. The water source multi-split air conditioning system further comprises a frequency conversion module cooling unit. The frequency conversion module cooling unit is arranged on the compressor frequency conversion module and used for guiding cooling water flowing out of the water source cooling unit to flow through the compressor frequency conversion module so as to absorb heat generated by the compressor frequency conversion module and make the cooling water which absorbs the heat flow back to the water source cooling unit through a cooling water inlet of the water source cooling unit. Duo to the fact that the water source multi-split air conditioning system makes the cooling water flowing out of the water source cooling unit flow through the frequency conversion module cooling unit so as to absorb the heat generated by the compressor frequency conversion module, the water source multi-split air conditioning system is capable of realizing safe and reliable heat dissipation of the compressor frequency conversion module, simple in heat dissipation structure, and quite low in cost.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a water source multi-connected air conditioning system. Background technique [0002] At present, multi-connected air-conditioning systems on the market are usually divided into air-sourced multi-connected air-conditioning systems and water-sourced multi-connected air-conditioning systems. Compared with the air source multi-line air conditioning system, the water source multi-line air conditioning system has higher energy efficiency ratio, less floor space, lower operating noise and vibration, and more stable and excellent performance. Therefore, the water source multi-line air conditioning system Air-conditioning system has gradually been favored by people. [0003] However, whether it is an air-source multi-connected air-conditioning system or a water-source multi-connected air-conditioning system, when the compressor is running, the electronic components of the frequ...

Problems solved by technology

[0006] However, in the actual use of the water source multi-connected air-conditioning system using the existing heat dissipation method, when the temperature feedback sensor fails or the fan fails, the entire heat dissipation control process will fail, and it is only to realize the frequency conversion module of the compressor in the electric control box. The additional cooling fans and temperature sensors also increase the cost of the entire system
