Résumé

The liquid receiver (LR) is a common accessory in heat pumps and refrigeration systems. Not only to accommodate excess of refrigerant to recovery from losses along time, but also to work with the optimum charge in systems where optimum refrigerant mass can vary at different operating conditions. Nevertheless, in the scientific literature, not many authors have paid attention to the influence of liquid receiver characteristics on the system performance and none of them has studied its influence during transient behavior due to changes in the operating conditions.
This work compares experimentally the effect of two different configurations designs of the inlet port for the liquid receiver. The differences are found in the shape of the inlet and outlet port inside the liquid receiver. The LR is installed in a heat pump for producing domestic hot water and working with propane, in such a systems the distribution of the charge is very important to
obtain great performance.
Results has shown that transient behavior differs highly depending on which LR configuration is used. For instance, the transient period last 35 minutes in one configuration, while in the other one takes less than 5 minutes.
