Absorption refrigerator with temperature control

摘要

A cooling unit constructed in accordance with one example of the present disclosure includes an outer shell that defines an interior volume. A cooling system cools the interior volume. A temperature sensor senses a temperature within the interior volume. A heating element is disposed within the interior volume. A controller communicates with the temperature sensor and the heating element and activates the heating element based on the temperature satisfying a threshold.

主权项

1. A cooling unit comprising:
a cabinet that defines an interior volume; a cooling system that cools the interior volume, the cooling system including an evaporator; a temperature sensor that senses a temperature within the interior volume; a heating element disposed within the interior volume and operably associated with the evaporator; and a controller that communicates with the temperature sensor and the heating element, wherein the controller activates the heating element based on the temperature satisfying a threshold; and wherein the controller further implements a low ambient temperature regulation control scheme by controlling the heater in accordance with the sensed temperature and during low ambient temperature conditions, to thus heat the evaporator, and as a result to cause the cooling system to provide cooling under low ambient temperature conditions where the cooling system would otherwise not provide sufficient cooling to cool the interior volume of the cabinet.
