Problems solved by technology

[0007] Although thermoelectric devices are inherently irreversible, due to the heat and current that must flow through a circuit during their operation, thermoelectric devices have no moving parts that make them extremely reliable and quiet

Embodiment Construction

[0018] figure 1 A refrigerated enclosure 20 is shown incorporating a glass door 22 that allows access to refrigerated products as well as provides a transparent function for the user to view the contents of the refrigerated enclosure 20 . Refrigerated enclosure 20 may include various construction elements, such as shelves 24 and the like. Cooled air circulates within the climate-controlled space of the refrigerated enclosure 20 to provide cooling to products that may be placed inside the refrigerated enclosure 20 . In addition, an air curtain is provided along the glass door 22 to prevent the ingress of outside air and the escape of cooling air to the surrounding environment during the time the door is open.

[0019] Return air duct 18 conveys air from the climate-controlled space of refrigerated enclosure 20 to a refrigeration system heated heat exchanger such as evaporator 30 . The air then flows back into the climate-controlled space of the refrigerated enclosure 20 throu...

Abstract

A controlled surface having a direct contact with a flow of cold air circulating within a climate-controlled space is provided. A thermoelectric device is associated with the controlled surface and has a hot junction positioned upstream in the path of the air stream moving over the controlled surface and a cold junction positioned downstream in the path of the air stream. This arrangement provides defogging, defrosting or condensate evaporation for the controlled surface, while the temperature in the climate-controlled space is not appreciably altered, and at least some amount of moisture is removed from the air stream by the thermoelectric device.

Description

【Technical field】 [0001] The present application relates to the use of a thermoelectric cooler for providing demisting or defrosting of cold surfaces associated with a climate-controlled space without significantly affecting the climate-controlled space condition inside. 【Background technique】 [0002] Various enclosure and enclosure structures include surfaces, which may be transparent or reflective, and are typically required to maintain this transparent or reflective function throughout the operating life, especially during air conditioning or refrigeration equipment operation. For example, in grocery stores, items are often displayed in refrigerated containers. Within a refrigerated container, a glass door typically seals the enclosed refrigerated space from the outside environment while allowing the contents of the refrigerated container to be displayed and accessed. Cooled air is circulated in the climate-controlled space of the refrigerated container. The door face...
