Application of Inverter in Central Air Conditioning

01 Background

Central air conditioning system is an indispensable and important part of modern buildings. With the improvement of people's living standards and the acceleration of urbanization, the application of central air conditioning system is becoming more and more extensive, and the market size is rising year by year.

In the past decade, the application scope of central air conditioning system has been continuously expanded. In addition to the traditional commercial and industrial fields, it also involves residential, medical, transportation and other fields. Energy saving, environmental protection, comfort and safety have become the main technical characteristics of central air conditioning system.

02 User demands

With the continuous advancement of technology, the energy efficiency ratio and performance coefficient of central air-conditioning systems have been continuously improved, and have also made significant contributions to energy conservation and emission reduction.

However, there are also some pain points in central air-conditioning system technology:

1. Energy saving: How to reduce energy consumption and improve energy utilization efficiency is the top priority of the current central air-conditioning system.

2. Intelligence: How to use intelligent technology to achieve automatic control and remote monitoring of central air-conditioning systems to maximize user satisfaction?

3. Diversification: How to make different types of central air-conditioning respond to different usage scenarios and thus meet user needs?

4. Safety: How to strengthen the safety performance of central air-conditioning and improve the safety, reliability and stability of the system?

03 Solutions 

The refrigeration principle of the central air conditioning system is liquid vaporization refrigeration, which is achieved by extracting part of the steam. The high-temperature gas raises the water temperature, condenses into liquid, and then evaporates into low-temperature gas, and circulates continuously to achieve refrigeration. The heating principle is that the compressor sucks in low-pressure gas and compresses it into high-temperature gas, raises the water temperature through the heat exchanger, and then condenses it into liquid. The liquid enters the evaporator and evaporates into low-temperature gas, which circulates continuously to deliver hot water to the room that needs heating to achieve heating.
