example 1

[0014] Example 1: The refrigerant R300 of the present invention is composed of 60% difluorochloromethane, 20% difluoroethane, and 20% propane. In the National Compressor Refrigeration Equipment Testing Center, 3 cabinets of American Philco (formerly used refrigerant R22 ) According to the national standard, the basic comparative refrigerant R22 test shows that the energy efficiency ratio of the unit is increased by 11.14% after using the working medium R300 of the present invention. (This is the highest among a large number of mixed refrigerants detected at home and abroad by the center as of September 20, 2000)

[0015] Example 2: In Jinhai Hotel, Hangzhou, the HR225 water chiller produced by Shanghai Hezhong Carrier Factory was replaced with the refrigerant of the present invention and compared with the original working medium R22 when it was compared and tested as follows:

[0016] 1. Test process:

[0017] (1) Run the unit using R22 and read the basic data of the system. ...

Abstract

An energy-saving environment protection type refrigerant is prepared from difluoromonochloromethane and two of propylene, 1,1-difluoroethane and propane through mixing in liquid state. Its advantages are no toxicity, no environmental pollution, no corrosion of equipment and high safety.

Description

technical field [0001] The invention relates to a refrigerant, in particular to an energy-saving and environment-friendly refrigerant. Background technique [0002] In the existing technology, R22, R12, R502, these excellent refrigerants are widely used in central air conditioners, household air conditioners, and low-temperature refrigeration and freezing equipment. The destruction of the ozone layer has also aroused more and more people's concerns. The Montreal Protocol clearly stipulates the use period and limits its ODP value, which makes the proposal of new refrigerants very important. Looking for environmentally friendly, energy-saving and convenient refrigeration Refrigerants are of great significance to scientists; my country is a big country in the world, and environmental protection is our responsibility, but at the same time, our country is a country lacking in energy. How to develop energy-saving and environmentally friendly refrigerants is very important to our...
