Problems solved by technology

[0004] Previous prior art systems have suffered from poor and inefficient temperature control, and complex systems have been found to be unreliable due to periodic failures
Additionally, the prior art system with its complex design has been found to be very heavy, which is undesirable during transport of the system and also makes installation more difficult

[0253] Example 1 - Specific Cooling Situation: Cooling of a Chamber

[0254] use figure 1 For the device shown, a vapor compression cycle has been developed to precool a phase change material (eg, magnesium sulfate) beyond its phase change temperature of -5°C, with the selected precooling end temperature being about -20°C. The system was then reversed to provide discharge cooling to a temperature controlled chamber at about -20°C. In this study, the thermal battery was drained when the condensation temperature reached ambient temperature.

[0255] Use algorithms to select phase change materials (PCMs) and / or refrigerants

[0256] now refer to Figure 12 , Figure 12 is a representation of a method (i.e. an algorithm) that allows selection of a phase change material (PCM) and / or refrigerant for a specific application. The method is divided into two pages on figure pages 12 / 13 and 13 / 13 and should be read together.

Abstract

The present invention describes a vapour compression apparatus wherein an intermediary located heat battery is capable of releasing charge (i.e. discharging) and / or charging and thereby controlling the temperature of a heat source or heat sink temperature in a vapour compression cycle. More particularly, the present invention describes vapour compression apparatus wherein an intermediary located heat battery comprising Phase change material (PCM) is capable of releasing charge (i.e. discharging) energy and / or charging and thereby controlling the temperature of a heat source and / or heat sink temperature in a vapour compression cycle in a range of refrigeration and / or heating systems including: air conditioning in both domestic and industrial uses; transportation of food / materials in vehicles, trains, air, etc. The present invention also relates to a methodology for selecting phase change materials (PCMs) and / or refrigerants for a vapour compression apparatus.

Description

technical field [0001] The present invention relates to vapor compression devices in which an intermediate thermal battery is capable of releasing (ie discharging) and / or charging and thereby controlling the temperature of the heat source or heat sink during the vapor compression cycle. [0002] More specifically, the present invention relates to a vapor compression device in which a thermal battery is located between an evaporator and a condenser, and the vapor compression device includes a phase change material (PCM) capable of releasing charge (i.e., discharge) energy and / or charge and thereby control the temperature of the heat source and / or the temperature of the radiator in the vapor compression cycle in a series of refrigeration and / or heating systems including: domestic and industrial air conditioners; Transportation of food / materials in vehicles, trains, aircraft, etc. The present invention also relates to a method for selecting a phase change material (PCM) and / or r...
