Hydrocarbon refrigerant containing ethanol

Abstract

The invention discloses a hydrocarbon refrigerant containing ethanol, which comprises the components by mass percent: 90-96% of propane, 2-7% of iso-butane, 1.5-2.8% of alcohol fatty oil and 0.2-0.5% of ethanol, wherein 90%, 93% or 96% of propane is preferred, 2%, 4.5% or 7% of iso-butane is preferred, 1.5%, 2.15% or 2.8% of alcohol fatty oil is preferred, and 0.2%, 0.35% or 0.5% of ethanol is preferred. The hydrocarbon refrigerant containing ethanol greatly improves the using safety of the hydrocarbon refrigerant, overcomes the oxidization of moisture inside the hydrocarbon refrigerant for a compressor, improves the efficiency and the lubricating degree of the compressor, is more beneficial to the safety and environmental protection of transition use from R22 refrigerant to the hydrocarbon refrigerant, and greatly improves the stability and the economical efficiency of a system.

Description

Technical field [0001] The invention relates to a refrigerant, especially a hydrocarbon refrigerant containing ethanol, which can directly replace the ethanol hydrocarbon refrigerant of R22. technical background [0002] According to the signing of the "United Nations Framework Convention on Climate Change", "Montreal Protocol" and "Kyoto Agreement". The protocol stipulates a total of six greenhouse gases, namely carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons and perfluorocarbon emissions. This poses new challenges for China, which is the main production and use of HCFC. Currently, alternative HCFC refrigerants are roughly divided into three categories, one is HFC refrigerants, the second is natural working fluids, and the third is HC refrigerants. The HFC refrigerant R410A is a non-fluorine environmentally friendly product. According to the latest implementation of the European Union's green environmental protection directive, all air condition...

Problems solved by technology

The annual sales volume of R22 refrigerant is more than 200,000 tons, and each steel cylinder needs to be filled with 5 kilograms, and 40 million bottles need to be filled, all of which are disposable and waste energy

The charging amount of hydrocarbon refrigerant is 45% of the mass of R22 refrigerant, and 18 million steel cylinders need to be manufactured per year. Calculated at a cost of 30 yuan for each special steel cylinder, it will cost 540 million yuan per year to manufacture steel cylinders. Consumption high energy consumption
