Refrigerant R290 you understand

Chinese name propane, belong to the hydrocarbon refrigerants, molecular formula C3H8, appearance colorless gas, tasted odourless, slightly soluble in water, soluble in ether, ethanol, flash point, ℃) - 104.

the explosion limit % ( V/V) 9. 5, lower explosive limit (% V/V) 2. 1, relative density, Air = 1) 1. 56, heat of combustion ( kJ/mol) : 2217. 8, ignition temperature ( ℃) : 450 ~ 470.

note: flash point, flammable liquid on the surface of the steam and air is a mixture of contact with the fire temperature and flash occurred for the first time. Health hazard:

there are simple asphyxia and anesthetic effect. 1% propane brief contact and do not cause symptoms; Concentration below 10%, only cause mild dizziness; Can appear when contact with high levels of anesthesia, loss of consciousness; High concentrations can cause choking.

dangerous features: flammable gas, mixed with air to form explosive mixture, with heat and flame is in danger of burning explosion, security level for A3.

filling quantity is small, the dosage of refrigerant R290 is only 40% ~ 55% of R22, R410A, less dosage, more economical. Energy saving:

low freezing point, more latent heat of evaporation, per unit time and cooling velocity faster; Small isentropic compression than power, make compressor work more easily, extend the service life of the compressor; Small molecular weight, good liquidity, lower delivery pressure, reduce the load of the compressor. Use of R290 refrigerants, energy-saving rate can reach 15-30%.

the above about the introduce of refrigerant R290 over here, hope to be able to bring you some help, if there is demand of R290 refrigerants, welcome consultation discussion with us, we wholeheartedly at your service.
