Abstract:

A numerical model of the hermetic reciprocating piston compressors that widely used in most cooling systems and air source heat pumps, has been developed. The model is based on the conservation equations, Thermodynamics laws, gas dynamics equations and Hydro-gas dynamics equations and piston and valves dynamics. Finite volume method is used to integrate the partial differential equations governing the flow, with a implicit approximation for transient terms, and control volumes are adopted for velocity components.The mathematical form equations that result from the integration of the governing differential equations over each control volume are solved. The iterative procedure evaluates flow properties for each time step until convergence is reached, which is ascertained by examining whether the compressor operation conditions are cyclically repeated. In the base of mathematical modeled and developed algorithm for compressor, program has written in FORTRAN programming language and has been realize in computer. Program consist main and sub programs.
