Abstract

<p>An adsorption refrigerator with a zeolite adsorbent can be regenerated using water at a low temperature of 45 to 60 ℃. In this refrigerator, the cold water outlet temperature fluctuates, and with increase in the cycle time, the fluctuation range becomes larger. Therefore, it may be difficult to use this in air conditioning applications or applications requiring accurate water supply temperature. In a previous study, the amount of cooling water supplied to a heat exchanger (HEX) coated with an adsorbent was varied to maintain a constant cold-water temperature at the outlet. However, it was found that the cooling capacity reduces after the subsequent cycle. In the previous system, when the amount of cooling water supplied to the HEX decreases, the amount of cooling water supplied to the condenser also decreases, because the HEX and condenser are connected in series through a cooling pipe. In this study, we installed a bypass route from the inlet side of the HEX to the condenser in order to maintain the amount of cooling water supplied to the condenser in a stable manner. Then, we measured the temperature change of the cold water and the cooling capacity. We confirmed that the mean deviation of the cold-water outlet temperature could be improved to within ±0.2℃ by reducing the output to 80-90% of the steady-state cooling capacity.　</p>
