The test system is the use of liquid refrigerant method to measure the water side heat transfer is calculated as formula (1). Uncertainty of the water side can be seen mainly from the water temperature and flow measurements, by this method are discussed in Section 2.5 to calibrate,<a href="http://www.edhardysdanmark.com" target="_blank" class="postlink">ed hardy bikini</a>, can significantly reduce the magnitude of measurement uncertainty, increase the credibility of measurement results. 4 Conclusion This paper introduces the technical exchange of groundwater water source heat pump design and manufacture of test systems meet the requirements of domestic standards, the program advanced, the structure is reasonable. The test system will use the heat source side to side and heat, making the maximum use of energy are to achieve energy-saving purposes; it has a high degree of automation, to achieve automatic control and regulation,<a href="http://www.abercrombiemilanohollister.com" target="_blank" class="postlink">Abercrombie and Fitch</a>, process monitoring, data acquisition and transmission software ; the entire test system in the test equipment on the basis of stable and reliable operation and ensure the precision and accuracy of the test. The establishment of this test system, greatly improving the test of the level of refrigeration and air conditioning industry for research and development of water source heat pump provides a rational design, testing, accurate, stable, reliable and energy-efficient test platform.
