Development of an Experimental Platform for Multi-source Complementary Heat Pump Heating System

Multi-source heating technology has the characteristics of highly efficient, energy saving and environmentally friendly, it utilizes renewable energies and now it's facing important development opportunities and urgent needs. This paper designs and develops a set of multi-source complementary heat pump heating system, which takes solar energy and air energy as main sources and electric energy as auxiliary heat source, and realizes various test conditions by switching between valves, including the test on the thermal performance of solar collectors, test on the performance of heat pump unit, test on the operating parameters of solar/heat-pump combined heating system, and test on the control characteristics of heating system, etc.; a variety of terminal combinations could be selected according to the requirements of the tests. During the tests, the test data can be measured and saved in real time, the proposed experimental platform provides a high-level scientific research platform for the innovative, comprehensive, and research-based tests.
