Summary
The unitary water source heat pump (UWSHP) is one of the most efficient, environmentally friendly ways to heat and cool buildings. It is composed of a scroll compressor, an indoor tube-fin heat exchanger (air cooled), a tube-in-tube heat exchanger (water cooled) and an electronic expansion valve. Based on the distributed parameter methods as well as mass conservation, energy conservation and pressure equilibrium, theoretical models of 4 main components and of the refrigeration system in UWSHP were established. The performance of a 3-kW UWSHP system for R-22 was simulated. Effects of flow rate and temperature of cooling water, indoor air temperature on the system performance were studied. The simulated results provide the basis for the optimal design of UWSHP components and system.
