New better design for water-water heat pumps

Abstract

Abstract.In air conditioning facilities most of the energy consumption corresponds to the thermal production, this being heat and cold. It depends on many factors, one of the most important in the use of more efficient devices (boilers, chillers and heat pumps)for supply thermal energy. In this work the efficiency of the reversible waterwater heat pumps is analyzed, proposing a new better design that optimizes the nergy consumptiom. This improvement hardly requires modifications at manufacturing, therefore, it could be easily developed by manufacturers.

Correlations for cost of ground-source heat pumps and for the effect of temperature on their performance

“…Furthermore, according to ref. , the degradation of performance can be mainly related to reversing the refrigerant flow direction in the expansion device and/or in the heat exchangers. A plausible explanation to the COP drop observed in the data when switching to the heating mode could be that the cooling mode being dominant in the North American market, the internal configuration of reversible heat pump models, is likely to be primarily optimized for this operating mode.…”
