Benefits of technology

[0015]In one embodiment, the cooling system may include a solenoid valve in conjunction with the inlet or outlet to provide pulsatile flow of the coolant fluid and improve cold transfer.

Problems solved by technology

It is known that a large amount of electric power is consumed by the cooling of residual and commercial buildings, especially during daylight hours.
Overall, a large imbalance in electric power usage exists during daylight hours, due primarily to the amounts of power consumed by industry, businesses, and public transportation.

Embodiment Construction

[0020]Embodiments of the cooling system use water as a phase change material where the water in liquid form provides sensible heat and the water / ice combination provides a latent heat of about 80 calories per gram. Water provides advantages over the use of other conventional phase change materials such as linear crystalline alkyl hydrocarbons as it has a higher latent heat and higher sensible heat, is much lower in cost, and is readily available.

[0021]Referring now to FIGS. 1A and 1B, one embodiment of the cooling system 10 is shown. As shown in FIG. 1A, the cooling system 10 comprises a shell 12 including a primary heat exchanger 14 therein which comprises a plurality of heat exchange pipes 16 including a phase change material 18 therein. The heat exchanger 14 is used in conjunction with a separate liquid to air heat exchanger 32 which is capable of supplying the cooling requirements of a residential home.

[0022]The shell 12 is preferably rectangular or cubic in configuration and sh...

Abstract

A cooling system is provided which includes a primary heat exchanger including heat exchange pipes filled with a phase change material comprising water. The heat exchange pipes are in heat transfer relation with a coolant fluid, which, upon cooling, is transferred to a separate liquid to air heat exchanger for conversion into cool air, for example, for use in air conditioning or refrigeration.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a cooling system, and more particularly, to a cooling system which utilizes phase change materials for the storage and release of thermal energy.[0002]It is known that a large amount of electric power is consumed by the cooling of residual and commercial buildings, especially during daylight hours. Overall, a large imbalance in electric power usage exists during daylight hours, due primarily to the amounts of power consumed by industry, businesses, and public transportation. To compensate for the extensive day time use of electric power, utility companies provide generating capacity sufficient to supply day time usage, leaving unused capacity available for the night hours.[0003]A need has arisen in the art for a cooling system which can provide more efficient cooling and which can make effective use of energy during off-peak hours. Cooling units are known which utilize phase change materials to provide more effective ...
