Abstract

The present invention relates to a remote refrigeration display case system including a display case, air flow passages, and a refrigeration system including a air condition duty compressor, a condenser, a expansion / throttle device, a evaporator, and pipes connecting these components, wherein the air condition duty compressor and the condenser are installed remotely, and the saturated evaporating temperature of the evaporator is -4 to 2 DEG C. With the present invention the display case system can reduce the power consumption by 20% and can be produced with lower cost. Furthermore, the display case system according to the above embodiment operates with lower noise level and higher reliability.

Description

Technical field [0001] The present invention generally relates to a remote refrigeration display cabinet system, which is used in the field of commercial cooling systems to display and preserve refrigerated food and the like. Background technique [0002] Usually, supermarkets and convenience stores are equipped with refrigerated display cabinet systems to display fresh food or drinks to customers. All refrigeration display cabinet systems include at least the following components: compressors, condensers, at least one evaporator associated with the display cabinets, expansion / throttling equipment (such as expansion valves) and suitable refrigeration pipes connecting these equipment. The expansion valve is provided in the pipe upstream of the refrigerant flow at the inlet of the evaporator to expand the liquid refrigerant. The function of the expansion valve is to expand the liquid refrigerant to the desired low pressure selected for the particular refrigerant before the refrige...
