Recently, the highly efficient extra-high temperature heat pump unit developed by Yantai Land Air-conditioning Industry Co., Ltd. passed the evaluation of the National Supervision and Inspection Center of Compressor and Refrigeration Equipment. The equipment uses special single refrigerant and thoroughly solves the problems such as temperature reduction of mixed refrigerants and inconvenient maintenance.

Under standard work conditions, the temperature of outlet water at the heat source side is 40°C, at the hot water side is 80°C, and the performance coefficient is 4.2 (standard is 3.0), and the thermodynamics coefficient is 0.385 (standard is 0.28), and the highest temperature of outlet water is up to 85°C. The equipment has a wider temperature range for the heat source water (28°C~58°C), and can be widely used in various fields such as geothermal tail water treatment and industrial waste heat application, etc.
