Central air-conditioning energy-saving transformation technology – Kling to teach you

The possible transformation of central air-conditioning is an important strategy for many industrial enterprises and other high-energy-consuming units to achieve energy-saving and efficiency reduction and reduce operating costs. Low risk and significant energy savings are the main reasons for the market. Xiaobian is here to introduce several common central air conditioning energy-saving technology transformation plans.

Central air-conditioning energy-saving transformation technology – Kling to teach you


1. Magnetic suspension central air conditioning technology

air cooled water chillers

Due to the application of magnetic levitation technology, the performance of the compressor has been significantly improved. The speed of the compressor can reach a very high speed of 48,000 rpm, and the overall volume and quality of the compressor are also significantly reduced. Secondly, the problem of lubricating oil recirculation is eliminated, and no Speed, a series of innovative design, magnetic suspension central air conditioning energy saving 50%, compared with the traditional air conditioning, its starting current is very low, system stability, service life of 30 years, making it the most popular form of central air conditioning energy saving.

Packaged rooftop unit supplier

For example, after a large-scale electronic enterprise in Kunshan, the central air-conditioning energy-saving renovation achieved 60% ultra-high energy-saving rate, saving more than 3 million yuan in annual electricity bills, and achieved good ecological, economic and social benefits.

Heat pump

2, heat pump technology


Heat pump technology is a technology that utilizes low temperature, low level heat sources. The principle of a heat pump is to convert low-level heat energy into high-level heat energy through a small amount of high-energy input, mainly including air source heat pump technology and water (ground) source heat pump technology. It can provide heating and cooling for buildings, effectively reduce the energy consumption of building heating and cooling, and reduce regional environmental pollution.

Equipment terminal

3. Adjustable technology for heating terminal equipment

It mainly includes terminal heat adjustable heat metering device, thermostatic valve connecting each heater, corresponding heat network control and regulation technology and application of variable frequency pump. It can achieve 30%-50% energy saving effect, and can avoid the problem of uneven heating and uneven heating at the end of heating.

Fresh air treatment

4. Fresh air treatment and air conditioning system waste heat recovery technology

Fresh air loads typically account for about 30% to 40% of the total building load. The cooling capacity required to change the amount of fresh air is about 20% less than the fixed minimum amount of fresh air. If the minimum amount of fresh air can be changed to fresh air, the energy consumption in spring and autumn can be reduced by nearly 60%. The exchange of heat and humidity between the exhaust and fresh air in the air-conditioned room is carried out by the total heat exchanger. Waste heat recovery from an air conditioning system can be achieved by cooling and dehumidifying the air in the air conditioning unit.

Air conditioning dehumidification

5, independent dehumidification air conditioning energy-saving technology

Central air conditioning dehumidification consumes 40%-50%. Increasing the cold water supply by 1 degree Celsius can increase efficiency by about 3%. With independent dehumidification, combined with air conditioning waste heat recovery, central air conditioning energy consumption can be reduced by more than 30%. Solution independent dehumidification air conditioning is a key technology developed in China.

In addition, there are building cogeneration technology, phase change energy storage technology, solar energy integrated building, etc. Energy-using enterprises can choose their own central air-conditioning energy-saving transformation methods according to actual conditions, including contract energy management and energy-saving transformation mode. At the same time, minimizing the investment risk of the owners and realizing the energy-saving renovation of central air-conditioning has become a reality, which has also led to higher, faster and more stable development of the energy-saving industry.
