I. Overview

The heat pump technology is one of the effective measures for recycling and using low thermal energy. Studying and promotion of heat pump technology is of great significance to energy conservation. With the development of refrigeration technology in recent years, heat pump technology has been applied in my country. This device can perform the refrigeration cycle process and heat pump demonstration, which can observe the phenomenon of evaporation, condensation process and compressor working phenomenon of refrigeration work.

This experimental system uses the performance of the thermal balance method to measure the performance of the heat pump and the refrigeration compressor. The system is m--nly composed of refrigeration compressor, evaporator, condenser, constant temperature water tank, and electronic expansion valve. Use sensors and detection instruments to collect temperature, pressure, flow, flow, compressor power, current, frequency and other status parameters in the process of steam compressed refrigeration cycle. The self -developed data collection board card is connected to the computer. The measurement and control software with high real-time, interface design and humanization, and other characteristics of thermal cycle dynamic display, performance parameter testing and calculation of the thermal cycle process constitute a multifunctional integration heat pump-compressor performance experiment with testing, analysis, recording, testing, drawing and other functional integration system. Based on basic units, the following content is added: student design and innovative experiments.
