OPTIMIZATION AND ANALYSIS OF THE URBAN SEWAGE SOURCE HEAT PUMP SYSTEM BY FINITE TIME THERMODYNAMICS THEORY

The areas of the sewage heat exchanger, the evaporator and the condenser are the important design parameters of the urban sewage source heat pump system(USSHPS). This paper establishes the mathematical models of optimal heating coefficient of performance (COP) of heat pump and minimal total heat exchanger area with the finite time thermodynamic theory and obtains the relationship of the parameters each other. By optimizing and matching each of the heat exchanger areas on the condition of the constant total heat exchanger area, it obtains the optimal characteristics for the sewage source heat pump system, such as the optimal heating COP. Similarly, by optimizing and matching each of the heat exchanger area on the condition of the definite characteristic, it obtains the minimal total heat exchanger area. At last, with an example, USSHPS is optimized and analyzed. The results present that rationally matching and choosing the heat exchanger areas have the important meaning for the improving the operational characteristic or the first cost of the USSHPS, and can give the helpful reference to the systems design and operation.
