WebIn this paper, one dimensional analytical models are described for an earth-air heat exchanger and an earth-water heat exchanger combined with a compact water-air heat exchanger. These models are used to study the influence of different design parameters (tube length, tube diameter, fluid flow rate, etc.) on the thermal-hydraulic performance. 2 ... WebThe calculations were conducted for the tested heat exchanger constructed of copper pipes and elbows and aluminium fins. The flow of air and refrigerant was counter-current with an in-line arrangement of the pipes. Refrigerant R290-propane was used. The geometry of the heat exchanger is shown in Figure 1 below and described in Table 1.
