Due to the frequency conversion compressor, the energy saving of the system is greatly improved. At present, the compressors of multi-line products in the industry are divided into two types: frequency conversion multi-unit and digital scroll.

What is the difference between these two types of air conditioners? Shanghai Air Conditioning Design Company will explain to you in detail:

Compared with the digital scroll, the variable frequency multi-connection has the characteristics of stable operation, high motor efficiency, and fewer compressor start and stop times. It can make the multi-line system under low load, the external machine reduces the compressor speed through the inverter controller, so that The whole machine is in a low power consumption state.

When the system is under high load, the whole machine runs at full speed, which reduces the indoor temperature in a short time and reduces the energy consumption of the system.

According to experiments, Hitachi inverter central air conditioners can save energy by 27% compared to traditional central air conditioners. Taking a 5HP machine as an example, the average annual actual operating cost can be reduced by about 1,000 yuan.

Having a healthy, comfortable, warm and quiet home space is the ideal that people generally pursue. Consumers can follow this principle to buy their own central air conditioner.
