Embodiment Construction

[0031] according to Figure 1 to Figure 6 Embodiments of the present invention will be described. In this embodiment, the case of being applied to a business-use horizontal (desktop) freezer is exemplified. First, based on figure 1 Describe the overall structure. Reference numeral 10 is the main body of the storehouse, which is made of a horizontally long heat-insulating box with an open front, supported by feet 11 arranged at the four corners of the bottom surface. The interior of the storage room main body 10 is separated from the left and right by the attached heat-insulating partition wall 12, the relatively narrow side on the left is the freezer compartment 13F corresponding to the first storage room, and the wide side on the right is the freezer compartment 13F corresponding to the second storage room. Chamber of refrigerator 13R. Moreover, although not shown in figure, the opening and closing of the front surface of freezer compartment 13F and refrigerating compartme...

Abstract

In a cooling storage building wherein from one compressor a refrigerant is selectively supplied to multiple evaporators respectively disposed in multiple storage rooms of varied thermal loads, to prevent any temperature rise of a storage room of higher thermal load. A liquid refrigerant from compressor (20) and condenser (21) is alternately supplied through three-way valve (24) to cooler (27F) for refrigeration room and evaporator (27R) for chillroom so as to carry out alternate cooling of the refrigeration room and the chillroom. Regardless of which one of the refrigeration room (13F) and the chillroom (13R) is first in reaching a lower limit set temperature, the refrigeration room (13F) (storage room of higher thermal load) is necessarily cooled last and the temperature thereof is decreased to the lower limit set temperature.

Description

technical field [0001] The present invention relates to a cooling storage having a plurality of evaporators and supplying refrigerant to these evaporators from one compressor, and to an operating method thereof. Background technique [0002] As such a cooling storage, for example, a freezing room and a refrigerating room are partitioned and formed in a thermally insulated storage main body, and evaporators are arranged in each room, and cooling is alternately supplied from one compressor to these evaporators. An example of which is shown in Patent Document 1 below. [0003] The refrigeration cycle of this type of refrigerator is as follows: The refrigerant is compressed by the compressor and liquefied by the condenser, and is alternately supplied to the evaporator for the freezer and the evaporator for the refrigerator connected to the outlet side of the three-way valve through a capillary tube. device. Both the freezer compartment and the refrigerator compartment stop the...
