Abstract As the environmental problems and the energy crisis in today's world is increasingly serious , heat pump water heater starts to attract the attention of the people due to its energy conservation and the environmental protection , and gets the recognition of people, at the same time it has achieved rapid development in recent years。Compared with the traditional water heater,the heat pump water heater has distinct advantages such as energy saving, environmental protection, security, and conform to the requirements of the modern society of energy saving, so the heat pump water heater has a big market。With the continuous development of heat pump water heater industry, emerging out of the many models and brands of heat pump water heater, this time, a set of heat pump water heater performance test system is particularly important。

This article mainly to Beijing kunlun state automation software company and development of the MCGS configuration software as a platform, to design a set of air source heat pump water heater performance testing system, implements the system of heat pump water heater heat, power consumption, performance index, the COP test parameters and so on。

First, after a large number of literature search and studying the air source heat pump water heater on the basis of the national standard, master the working principle of air source heat pump water heater;Second, in laboratory, this paper analyzes the air source heat pump water heater, in accordance with the requirements of test system for the overall scheme design;Followed by a hardware design and the selection, this test system hardware adopts dry wet bulb temperature sensor, inspection instrument, computer and other equipment;Then the detailed design of software and design flow chart of the test, the test interface are finished, i write the test strategy script, and test the software。

Finally i have carried on the software and hardware alignment, and use the checking instrument and PC for the testing system of actual operation and test。Test results show that the test system can complete to COP of the air source heat pump water heater performance index measurement, the desired design is up to the requirements。

Key words: heat pump water heater;The MCGS。The COP;The test system
