ABSTRACT
The aim of this paper is to get a best performance by an ice block/cube making machine of refrigeration with suitable time. In present day hotels, resort and bar require more ice in very less time. So, to solve this problem and control the required time to ice formation, we construct an ice cube making machine. In present days, in market this machine is available with very high cost. So we try to make it at optimum price.
Ice making machine consists of four key components; the evaporator, the condenser, the compressor and the throttle valve. The compressor is to compress low pressure refrigerant vapor into high pressure vapor and deliver it to the condenser. The high pressure vapor is condensed into high pressure liquid and drained out through the throttle valve to become low pressure liquid. At this instant the liquid is conducted to the evaporator where heat exchanging occurs and ice is created. This is one complete refrigeration cycle. Ice making machine works on an ideal vapor compression cycle.
A field study of an ice cube making machines in restaurants confirmed that the ice production (i.e. compressor operation) was always coincident with utility peak periods. The measured duty cycles, combined with the actual electric load profiles, demonstrated the potential for off-peak operation in addition to energy saving by using more efficient machines.

INTRODUCTION
An ice block/cube making machine may refer to either a consumer device for making ice found inside a home freezer; a stand-alone appliance for making ice or an industrial machine for making ice on a large scale. The term "ice block machine" usually refers to the stand-alone appliance. This would include the evaporator and any associated drives/controls/sub frame that are directly involved with making and ejecting the ice into storage bin. An ice block/cube making machine, however, particularly if described as 'packaged' would typically be a complete machine including refrigeration and controls, requiring only connection to utilities.
