We specify a problem related to refrigerators operating in winter. We consider operation of a vapour compression refrigerator featuring a classic throttling device, a capillary tube. We supply the results obtained during an experiment using the capillary tube when the ambient temperature was below –35 degrees centigrade. We state the primary disadvantages of the refrigeration method under study. We provide suggestions for employing capillary throttling devices.
