Maximum 155 ℃! Three major cases to see how high-temperature vortex compressors help industrial heat pumps break free from their cocoon and become butterflies

Against the backdrop of accelerating global carbon neutrality, the industrial heat sector is undergoing disruptive changes. According to the International Energy Agency (IEA), industrial heat consumption accounts for 52% of global terminal energy demand, with fossil fuels accounting for as much as 74%. 

As the only technological path that can achieve 100% zero carbonization of industrial heat energy below 150 ℃, industrial heat pumps are expanding their market size at an average annual growth rate of 18%. High temperature heat pump technology can elevate medium and low temperature waste heat to 150 ℃ high-temperature steam, replacing traditional boilers to achieve a 60% recyclability rate, which is a key solution to low waste heat utilization. It is expected that by 2030, the global installed capacity of industrial heat pumps will exceed 120GW, forming a billion dollar market blue ocean. 

Development of compressor technology: Breaking through the high-temperature exclusion zone of heat pumps

Traditional heat pump technology is limited by heating temperature (usually ≤ 90 ℃), making it difficult to meet the process requirements of industries such as chemical and pharmaceutical. The high-temperature heat pump compressor has made optimization breakthroughs in high-temperature resistant motors, vortex disc design, high-temperature lubricating oil, efficient motor cooling scheme, and ensuring smooth lubricating oil return. It has launched a high-temperature compressor with a maximum condensing temperature of 155 ℃, and the hot air/steam temperature at the application end can reach 145 ℃ or above. It has strong advantages in high-temperature drying, high-temperature hot water preparation and other fields. This technology can not only meet the high temperature requirements in industrial production, but also make a huge contribution to energy conservation and emission reduction. 

High temperature vortex compressors can be used in hot areas below 150 ℃ through heat pumps

 Case 1: Before the energy-saving upgrade and transformation of the electroplating plant

 the electroplating materials were soaked in a 100 ℃ immersion pool before being electroplated, and then entered the electroplating equipment for gas heating for electroplating. The high-temperature materials after electroplating were cooled in a cooling pool. After energy-saving renovation, waste heat recovery is achieved through heat pumps to maintain the corresponding water temperature of the cooling pool and soaking pool. The unit adopts R245fa refrigerant compressor (YW470L1G-V100), with a maximum condensing temperature of 135 ℃ and a maximum evaporating temperature of 75 ℃, which can generate high-temperature hot water above 130 ℃. When the evaporation temperature is 65 ℃ and the condensation temperature is 130 ℃, the heating capacity is 70kW, the COP is as high as 3.4, and the energy-saving effect is significant. 

Case: 2: The production process of printing, spraying, energy-saving, emission reducing sheet metal

        printed materials requires hot air above 120 ℃ for drying. The return air after drying contains pollutants that need to be treated before being discharged, resulting in a large amount of heat waste. By using a high-temperature heat pump to recover the heat from the exhaust while meeting the requirements for the outlet temperature, the goal of energy conservation and emission reduction can be achieved. The unit adopts R1233zd (E) refrigerant compressor (YW390M1G-V100), with a maximum condensing temperature of 155 ℃ and a maximum evaporating temperature of 85 ℃, which can generate high-temperature hot air above 145 ℃. When the evaporation temperature is 80 ℃ and the condensation temperature is 150 ℃, the heating capacity reaches up to 63kW and the COP is as high as 2.8, with significant energy-saving effects and reduced exhaust emissions.

 Case 3: Mantou manufacturers safely produce 

traditional Mantou manufacturers use gas-fired boilers or coal-fired boilers to produce high-temperature steam, and the steam generated by the steamer is directly discharged after heat exchange by the steamer cage drawer, which is a huge waste. The customer uses 2 YIW72CI-V100 as the low-temperature stage and 1 R245fa refrigerant YW470L1G-V100 compressor as the high-temperature stage, with a maximum condensation temperature of 135 ℃ and the ability to generate high-temperature steam above 120 ℃. The energy cost of steaming Mantou is 0.012 yuan/piece, which is significant compared with 0.06 yuan/piece of natural gas energy. With the technological advancement of compressors and related industries, industrial heat pumps are expected to develop towards higher temperatures, greater heating output, higher energy efficiency ratios, and more intelligent directions.
