R407c

R-407c is a mixture of hydrofluorocarbons used as a refrigerant. It is a zeotropic blend of difluoromethane (R-32), pentafluoroethane (R-125), and 2- tetrafluoroethane (R-134a). Difluoromethane serves to provide the heat capacity, pentafluoroethane decreases flammability, tetrafluoroethane reduces pressure. Bij koudemiddelen wordt onderscheid gemaakt in natuurlijke koudemiddelen en synthetische koudemiddelen. R410A is een koudemiddel dat het vroegere R407C vervangt.

Dit verving het verboden freon chloordifluormethaan (R22) volgens het Montrealprotocol.

Het wordt gebruikt in koelmachines die koelen tot 0°C, zoals koelkasten en airconditioners. The ozone depletion potential (ODP) of a chemical compound is the relative amount of degradation to the ozone layer it can cause, with trichlorofluoromethane (R-or CFC-11) being fixed at an ODP of 1. Chlorodifluoromethane (R-22), for example, has an ODP of 0. CFC 1 or R- has the maximum potential . A refrigerant is a substance or mixture, usually a flui used in a heat pump and refrigeration cycle. In most cycles it undergoes phase transitions from a liquid to a gas and back again.

Many working fluids have been used for such purposes. Fluorocarbons, especially chlorofluorocarbons, became commonplace in the 20th .

R407C is een zeotropisch mengsel bestaande uit R3 R1en R134a. Het heeft eigenschappen die vergelijkbaar zijn met die van R2 en daarom, gezien wijdverbreide gebruik in Europa door de snelle Rfase. Het glide en warmteoverdracht kenmerken, als regel, . These refrigerants are used mainly for air conditioning and substitution of Rin many applications.

R134a has a relatively low pressure an thus, about more compressor displacement is necessary, when compared to Rand this can make a compressor more costly. Large tube components an as consequence, .

What is an Ultrasonic Leak Detector ( )? An Ultrasonic Leak Detector is a leak detector based on ultrasound. The Detector detects the high frequency sound a gas makes when it is leaking. What types of gasses does it detect?
