Embodiment Construction

[0017]While this invention is susceptible to embodiment in many different forms, it is shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not to be limited to the specific embodiments described.

[0018]FIG. 1 illustrates an embodiment of a thermal energy storage and cooling system with an isolated evaporator coil in a secondary refrigerant loop. This embodiment may function with or without an accumulator vessel or URMV 146 (universal refrigerant management vessel), and is depicted in FIG. 1 with the vessel in place in the primary refrigerant loop with the air conditioner unit 102.

[0019]As illustrated in FIG. 1, a conventional air conditioner unit 102 utilizes a compressor 110 to compress cold, low pressure refrigerant gas to hot, high-pressure gas. Next, a condenser 111 removes much of the heat in the gas and di...

The disclosed embodiments provide a refrigerant-based ice storage system with increased versatility, reliability, lower cost components, reduced power consumption and ease of installation.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is based upon and claims the benefit of U.S. provisional application No. 61 / 056,693, entitled “Thermal Energy Storage and Cooling System with Isolated Evaporator Coil,” filed May 28, 2008, the entire disclosure of which is hereby specifically incorporated by reference for all that it discloses and teaches.BACKGROUND OF THE INVENTION[0002]With the increasing demands on peak demand power consumption, ice storage has been utilized to shift air conditioning power loads to off-peak times and rates. A need exists not only for load shifting from peak to off-peak periods, but also for increases in air conditioning unit capacity and efficiency. Current air conditioning units having energy storage systems have had limited success due to several deficiencies, including reliance on water chillers that are practical only in large commercial buildings and have difficulty achieving high-efficiency. In order to commercialize advantages of...
