Get this from a library. Analytical modeling of heat pump units as as design aid and for performance prediction. [Jack Edwin Flower; Lawrence Livermore Laboratory.]. This paper introduces a novel design and performance prediction tool for the ground source heat pump (GSHP) system.
This tool features, a user-friendly. Three out of five heat pumps (Units A, B, and D) use the refrigerant Ra, while Units C and E use Ra. Units A, B, and D use a wrapped tank heat exchanger where the condenser coils the encircle outside of the storage tank.
Unit E uses an immersed heat exchanger where the condenser coils are located within the water storage tank. Research tool for use in the steady-state simulation and design analysis of heat pumps and air conditioners.
The program can be used with most of the newer HFC refrigerants as well as with HCFCs and CFCs. The standard vapor-compression cycle is modeled with empirical representations for compressor performance and first-principle region-by-region modeling of.
Heat Pump Conceptual Study and Design Overall assessment and further work Problem area The classical method for spacecraft thermal control is that the waste heat is conducted to the radiator, where it is radiated to space.
Therefore, the radiator temperature must be lower than the equipment temperature. A Heat Pump uses a. Modeling and Verification of Heat Pump Performance for Industrial Ener on *FREE* shipping on qualifying cturer: Publisher Unknown.

The cooling circuit, i.e. the heat pump, is in the centre of the heat pump heating - cooling system. A heat pump consists of the four main components: evaporator, compressor, condenser and expansion valves. The refrigerant is the working fluid of heat pumps. In the evaporator, the refrigerant takes over the heat from the low-temperature primary File Size: KB.
