A multi-outlet soft frozen dessert apparatus for a self-service restaurant with multiple freezers attached to the wall dividing the client area of the restaurant from the kitchen area is provided. The freezers of apparatus may include an evaporation tube comprised of an aluminum alloy micro-channel parallel flow extruded tape. The mix vats of the apparatus may include circulating water in a hydraulic system having added antifreeze to suppress a freezing temperature in the range of &#x2212;2&#xb0; C. to &#x2212;5&#xb0; C. to assure adequate approach temperature to cool a mix in the mix vat. The apparatus may include scrape blades mounted on a helical part of the beater-scraper that scrape a thin layer of ice crystals from an internal surface of the inner cylinder and fold the ice crystals inside the mix bulk.

A modular evaporator which can be assembled from a number of standard modules is provided. Depending on the requirements, the modular evaporator can be assembled to meet a wide range of design cooling loads. Additionally, the modular evaporator is capable of generating and holding ice for thermal storage purposes, eliminating the need for external ice storage tanks. Furthermore, the heat transfer and thermal storage fluid for the evaporator can simply be water which considerably simplifies the system, lowers the cost, and increases the efficiency of the heat transfer loop.

Modular evaporator and thermal energy storage system for chillers

The invention comprises a Thermal Energy Module comprising a tank adapted to hold water or other heat transfer medium (such as water), a water loop for introducing the heat transfer medium and removing the heat transfer medium, and a refrigeration loop comprising a heat exchanger further comprised of an inlet manifold, a heat transfer structure (such as a micro channel or pipe-in-plate panel) and an outlet manifold wherein the heat exchanger is adapted to transfer thermal energy between the heat transfer structure and the heat transfer medium. The Thermal energy Module may be utilized as a component of a heating and cooling system. Such a Thermal Energy Module may be used to store thermal energy during the day and return it during the evening. Additionally, such a Thermal Energy Module may be implemented as an array of such modules and such array of modules may be adapted to fit within the walls of a building or structure.

Thermal energy module

A control system measures the pressure/temperature of the refrigerant within a Thermal Energy Module having a heat exchanger and calculates the thickness of ice within the Thermal Energy Module. A controller calculates an integral starting from the moment when ice accumulation begins: I(t)=&#x222b;Tr(&#x3c4;)*d&#x3c4; where Tr is the refrigerant saturation temperature changing with time t. The thickness of the ice on one side of the heat exchanger can be calculated using the following formula: X=&#x221a;(2*I*K*Ui/&#x3c1;i/ci) where Ui is the thermal conductance of ice &#x3c1;i is the density of the ice Ci is the latent heat of the ice K is a correction coefficient associated with the type of the heat exchanger.
