There’s no doubt that the increasing popularity of CO2 heat pumps in commercial heating in China represents significant opportunities for Kaori. The company’s CO2 heat pump, which is showcased amid an impressive line-up at Chillventa 2014, can reach COP as high as 4.6 and can operate at ambient temperature of between -20°C ~ 43°C. 

A leading thermal and hydrogen technology company, Kaori has entered the market with the express purpose of targeting commercial public facility heating applications. Currently in China, COheat pumps are mainly used in commercial space heating and hot water for public buildings, hospitals, universities and rail transport.

Given the diverse climate zones in China, the country’s southern warmer ambient temperatures provide the most suitable conditions for CO2 heat pumps to operate. But Kaori’s solution also targets the cold temperatures in Northern China, where CO2 as a refrigerant is ideal, given its solid performance under ambient temperatures as low as -20°C. In addition, Kaori’s CO2 heat pumps can operate at ambient temperatures as low as -20°C to 43°C. 

The heat pump has heating capacity of 70kW and can be applied in a wide variety of facilities, including hotels, pools, government buildings, agriculture production, and pre-heating. Energy savings and reduced running costs, as well as an impressive COP of 4.6, have been achieved. 

Kaori quality paired with Japanese and German precision 

 The model introduces the latest technology with components from Germany and Japan, in addition to Kaori’s own CO2 plate heat exchanger: 

  • High efficiency exhaust fan with variable speed controls and low noise 
  • Control panel designed by Kaori with remote monitoring systems and automation of energy management with safety lock 
  • Kaori designed compact CO2 plate heat exchanger with corrosion resistance
  • Semi-hermetic reciprocating compressors for CO2 with low vibration and high efficiency (made in Germany)
  • Electronic expansion valve for precision flow control, power saving design (made in Japan)

Demand rising for CO2 heat pumps in China 

In light of the increasing concern over environmental protection, the demand for heat pumps in China is experiencing rapid uptake. In May 2014, the State Council published the ‘Energy Saving and Reduce Carbon Emission Development Action Plan’, which aims to phase-out 50,000 units of boilers in 2014 and 200,000 steam tons pos-2015. In the government’s 12th five-year plan for energy saving and environmental protection for industry development (released in 2012), CO2 heat pumps are listed as one of the key technologies to lead the industry in significant energy savings. 

Since 2011, China has become one of the leading markets in the world for heat pumps and the number of shipments is soon expected to represent the largest market in the world. In 2012, air-to-air heat pumps made up 85% of the domestic air conditioning market, while ground source heat pumps rose from practically zero market share in 2000 to more than €9.8 billion market value by 2015. Meanwhile, heat pump water heaters account for 3.2% of the total domestic water heater market with total sales expected to increased from €42million in 2003, to €420million by 2020. In regards to heat pumps in commercial applications the sales figures account for almost €4 billion in 2014.
