Problems solved by technology

Therefore, similar to the above, there is a problem that the temperature of the evaporator is significantly lower than the indoor temperature of the refrigerator, and the power consumption of the freezer and refrigerator is large.
However, when the radiator placed in the high-temperature part of the refrigeration cycle system is defrosting, it is placed in the low-temperature part, and there is a problem of condensation on the radiator and the back panel.
[0027] In addition, according to the freezer-refrigerator disclosed in the above-mentioned Patent Doc...

Embodiment Construction

[0162] Embodiments of the present invention will be described below with reference to the drawings. figure 1 It is a side sectional view which shows the freezer-refrigerator of 1st Embodiment. The freezer-refrigerator 1 is provided with a refrigerator compartment 2 for refrigerated storage of stored goods in an upper portion. Below the refrigerator compartment 2 is provided a vegetable compartment 3 which is kept at a temperature higher than that of the refrigerator compartment 2 and suitable for storing vegetables. In the lower part of the freezer-refrigerator 1, a freezer compartment 4 for freeze-preserving stored items is disposed. The front surface of the refrigerator compartment 2 is opened and closed by a rotary insulating door 2a. The front surfaces of the vegetable compartment 3 and the freezer compartment 4 are opened and closed by pull-out insulating doors 3a, 4a integrated with the storage cabinets 3b, 4b, respectively.

Abstract

A freezer-refrigerator comprising: a refrigeration compartment (2) for refrigerating and storing an object to be stored; a freezing compartment (4) for freezing and storing an object to be stored; a first compressor (11) for operating a first refrigeration cycle (10) in which a first refrigerant flows; a first heat dissipater (12) provided to a high-temperature section of the first refrigeration cycle (10); a first evaporator (14) provided to a low-temperature section of the first refrigeration cycle (10); a second compressor (21) for operating a second refrigeration cycle (20) in which a second refrigerant flows; a second evaporator (24) provided to a low-temperature section of the second refrigeration cycle (20); and an intermediate heat exchanger (31) for performing heat exchange between the low-temperature section of the first refrigeration cycle (10) and a high-temperature section of the second refrigeration cycle (20). The first evaporator (14) cools the refrigeration compartment (2), and the second evaporator (24) cools the freezing compartment (4).

Description

technical field [0001] The present invention relates to a freezer-refrigerator having first and second evaporators for cooling a refrigerator compartment and a freezer compartment, respectively. Furthermore, the present invention relates to a cooling store having first and second cooling chambers with different temperatures. Background technique [0002] Patent Documents 1 and 2 disclose conventional freezers and refrigerators. The compressor for a freezer-refrigerator disclosed in Patent Document 1 flows a refrigerant to operate a refrigeration cycle system, and first and second evaporators are arranged in parallel in a low-temperature portion of the refrigeration cycle system. The first evaporator is arranged behind the freezing compartment. By driving the blower, cold air generated by heat exchange with the first evaporator is circulated in the freezing chamber and the refrigerating chamber, thereby cooling the freezing chamber and the refrigerating chamber. The second...
