Environmental protection
        Before refrigeration system designers to environmental protection often do not pay enough attention, nowadays more and more people have realized the relationship between environment and sustainable economic development, and the refrigeration environment also put forward higher requirements. Therefore, the design of refrigeration system and refrigeration method selection should carefully consider the following aspects: the selection of refrigerant application of refrigeration for human and biological hazard; refrigerant on the environment, such as destruction of the greenhouse effect and ozone layer; at the same time, also must consider the effects of vibration and noise of the Phoenix refrigerator refrigeration device running the.
System initial investment
        For users, to achieve the same cooling requirements, obviously the less the better initial investment. Practice shows that the temperature range of cooling capacity, the same, the different methods of a refrigeration fan of the Great Wall industrial investment is not the same, sometimes even a big difference, therefore, it should be a typical conventional, refrigeration method of different kinds of comparative analysis. Especially in the construction of refrigeration engineering after the special requirements, should be in-depth analysis of various programs.
Cost of operation management
        For large refrigeration capacity, long running time of the refrigeration plant, its operation and management costs are the focus of consideration, is the key to the overall economic impact of the system. Due to the different performance and characteristics of various refrigeration methods, the annual operating management fees are not the same. Economic and technical analysis of the various schemes should be noted when designing alternatives.
Convenience of operation and maintenance
        Different refrigeration methods will be used to design different refrigeration devices, their operation regulation and the convenience of daily maintenance are also different. Design system, should consider the convenience of operation and maintenance.
        In addition, for the special field, focus on the choice of the system will be different. As for medical instruments, military equipment or technology research, economic system may not be the most important, and the operational safety and reliability will be the ultimate measure of system performance; cooling of microelectronic devices is more emphasis on miniaturization of refrigeration equipment and easy operation. So choose the suitable final cooling method, need to fully understand the basic principle and characteristics of various methods on the analysis on the comprehensive investigation of Jining ground source heat pump refrigeration, various factors which ultimately determine.
