“…For computational calculation, the governing equations were discretized using Equations (24)- (26), and the results are given by Equations (27)- (30), which correspond to Equations (20)- (23). For the stable analysis condition, the time interval (∆t) must be higher than the minimum time step in Equation 31.…”

The purpose of this study is to investigate the suitable operation and performance of a thermoelectric radiant panel (TERP) in the heating operation. First, the hypothesis was suggested that the heating operation of TERP can operate without a heat source at the cold side according to theoretical considerations. To prove this hypothesis, the thermal behavior of the TERP was investigated during the heating operation using a numerical simulation based on the finite difference method. The results indicated that it is possible to heat the radiant panel using a thermoelectric module without fan operation via the Joule effect. A mockup model of the TERP was constructed, and the numerical model and hypothesis were validated in experiment 1. Moreover, experiment 2 was performed to evaluate the necessity of fan operation in the heating operation of TERP regarding energy consumption. The results revealed that the TERP without fan operation showed the higher coefficient of performance (COP) in the heating season. After determining the suitable heating operation of the TERP, prediction models for the heating capacity and power consumption of the TERP were developed using the response surface methodology. Both models exhibited good R2 values of >0.94 and were validated within 10% error bounds in experimental cases. These prediction models are expected to be utilized in whole-building simulation programs for estimating the energy consumption of TERPs in the heating mode.

“…The two factor interactions showed high significance (i.e., p-value < 0.05) on heat exchange effectiveness at the cooling (i.e., evaporator) and the heating (i.e., condenser) sides of the TEM heat pump. Equations (11) and (12) are the proposed models that return the heat exchange effectiveness at the cooling side and heating side of the TEM heat pump, respectively. The model coefficients are summarized in Table 5, and the valid ranges of each model parameter are described in Table 6.…”

“…Total 32 experiment sets with 2060 data samples were acquired and used for the model validation. For validating the proposed empirical models, heat exchange effectiveness values (ε c , ε h ) were initially predicted by using the proposed models (i.e., Equations (11) and (12)), based on inlet water temperatures (T c,in , T h, n ), the water block temperatures (T c,surf , T h,surf ), and NTU values (NTU c , NTU h ) measured at the cooling and heating sides in the additional measurements. Then, by using Equations (1) and 2, outlet water temperatures (T c,out , T h,out ) leaving the TEM heat pump were predicted for comparing them with the actual outlet temperatures that were measured in the additional experiments.…”

This study aims to estimate the performance of thermoelectric module (TEM) heat pump for simultaneous liquid cooling and heating and propose empirical models for predicting the heat exchange effectiveness. The experiments were conducted to investigate and collect the performance data of TEM heat pump where the working fluid was water. A total of 57 sets of experimental data were statistically analyzed to estimate the effects of each independent variable on the heat exchange effectiveness using analysis of variance (ANOVA). To develop the empirical model, the six design parameters were measured: the number of transfer units (NTU) of the heat exchangers (i.e., water blocks), the inlet water temperatures and temperatures of water blocks at the cold and hot sides of the TEM. As a result, two polynomial equations predicting heat exchange effectiveness at the cold and hot sides of the TEM heat pump were derived as a function of the six selected design parameters. Also, the proposed models and theoretical model of conventional condenser and evaporator for heat exchange effectiveness were compared with the additional measurement data to validate the reliability of the proposed models. Consequently, two conclusions have been made: (1) the possibility of using the TEM heat pump for simultaneous cooling and heating was examined with the maximum temperature difference of 30 • C between cold and hot side of TEM, and (2) it is revealed that TEM heat pump has difference with the conventional evaporator and condenser from the comparison results between the proposed models and theoretical model due to the heat conduction and Joule effect in TEM.
