Refrigerants for vapour compression refrigeration systems

Resonance, 2012
With the mandate of Montreal Protocol banning ozone depleting substances, and Kyoto Protocol later on curtailing the use of substances which contribute to global warming, conventional refrigerants are to be replaced by environment-friendly working fluids.

Refrigeration system including refrigerant noise suppression

The Journal of the Acoustical Society of America, 1990
A refrigeration system comprising in closed series-flow relationship, a condenser, a capillary tube flow restrictor, and an evaporator including means connecting the outlet end of the restrictor to the evaporator inlet for reducing the noise generated by refrigerant flowing from the restrictor.

Study of Refrigerant Leakage in Refrigeration System

Journal of Fire Sciences, 2002
In this paper, a method to calculate the leakage of the flammable refrigerants in the refrigeration system by simplifying the leaking process using hydromechanics is put forward. Based on the efflux theory, it also calculates the velocity and concentration fields of the refrigerant, and points out the existance of FOECA.

New refrigerants and system configurations for vapor-compression refrigeration

Science, 2020
The high global warming potential of current refrigerants in cooling equipment based on the vapor-compression cycle has triggered a major effort to find and implement more environmentally benign alternatives. Here, we review the basics of the vapor-compression cycle together with the safety, environmental, and thermodynamic constraints that have led to

Refrigeration system optimization

International Journal of Refrigeration, 1987
Abstract It must first be established that refrigeration is necessary and that the required cooling cannot be achieved more cheaply by other means. The operating costs of a refrigeration system depend mainly on power consumption and this can be reduced by a wide variety of methods. The operating and capital costs should be brought together in the net

Aircraft Refrigeration Systems

Aircraft Engineering and Aerospace Technology, 1961
REFRIGERATION in aeroplanes does not, so far, involve the use of any techniques which have not already been established and used in other fields. These techniques must be considerably extended, however, and the features which distinguish this branch of refrigeration from others are that:
