Embodiment Construction

[0023] figure 1 A general flow diagram of the coolant / refrigerant system of an ice maker such as those that are the subject of this invention is depicted. figure 1In the closed coolant / refrigerant system 10 containing the coolant / refrigerant, the compressor 20 within the coolant / refrigerant system 10 is filled to a suitable level with a suitable gaseous coolant / refrigerant. The compressor 20 increases the pressure of the coolant / refrigerant thereby increasing the temperature of the coolant / refrigerant. As the compressor 20 pressurizes the entire system, the coolant / refrigerant exits the compressor 20 and passes along it to the condenser 30 where the high pressure coolant / refrigerant releases its heat and liquefies. The high-pressure coolant / refrigerant releases its heat via ambient heat exchange with the environment in the form of the high-pressure coolant / refrigerant passing through the serpentine-like coils of the condenser. The coolant / refrigerant leaves the condenser a...

Abstract

Disclosed are ice making machines which use aluminum as an alternative to copper in the ice making machine evaporator and also use an alternate coolant / refrigerant specifically targeted to provide improved heat transfer transport properties and higher heat capacitance than conventional HFC coolantlrefrigerants. Optionally, rotary compressors are used in place of conventional reciprocating compressors, further enhancing performance for the ice making machine. The disclosed ice making machines maintain high efficiency and ice output and provide equal or better energy efficiency than comparative ice making machines. At the same time, savings are realized in the material cost for the evaporator, and resulting from the combined effects of lower density and lower metal cost / unit weight offered by aluminum as compared to copper.

Description

[0001] Application for cross-reference [0002] This application claims priority to US Provisional Application No. 61 / 596,760, filed February 9, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to ice making machines, and in particular to ice making machines using different types of compressors, while the composition of aluminum in the evaporator not only as a replacement for copper but also as an alternative coolant / refrigerant, which in particular Designed to provide improved heat transfer transfer characteristics and higher heat capacity compared to common HFC (freon) coolants / refrigerants. For a given size ice maker, the resulting ice maker of the present invention maintains high efficiency and ice production and provides equal or better energy efficiency than commonly used ice makers of similar size currently in use, At the same time, savings in material cost can be achieved because aluminu...
