Refrigeration device and temperature control method of cold rooms thereof

Abstract

The invention discloses a refrigeration device and a temperature control method of cold rooms thereof. The refrigeration device comprises a first cold room, a refrigerating room, a second cold room and an evaporator room, wherein the top part of an upper vertical partition is provided with an air supply opening and the bottom part of the upper vertical partition is provided with a return air opening; an air duct and a fan are arranged in an air flow distributing plate; the air duct has a first air branch duct leading to the refrigerating room and a second air branch duct leading to the electric air door of a transverse partition; and the second air branch duct leading to the air supply opening on the top part of the upper vertical partition and is provided with an air supplying opening which is positioned above the transverse partition and leads to the second cold room. In the refrigeration device of the invention, only two air branch ducts are needed to be arranged for controlling the first cold room, the second cold room and the refrigerating room, and the air duct structure is simple and occupies small space in a cabinet. The temperature control method of the cold rooms of the refrigeration device is simple and can meet the requirements of various service states.

Description

technical field [0001] The invention relates to a refrigerating device and a control method for a refrigerating room thereof. Background technique [0002] The Chinese invention application with application number 200810111187.7 discloses a refrigeration device and its air volume distribution plate. The inner tank of the refrigeration equipment includes an evaporator room and three refrigeration rooms, that is, a small refrigerator room on the upper left side, a freezer room on the lower left side and a large refrigerator room on the right side, wherein the small refrigerator room on the upper side and the lower refrigerator room The side freezer is separated by a horizontal partition, the right large refrigerator is separated from the left small refrigerator and freezer by an upper vertical partition and a lower vertical partition, and the inner evaporator chamber is separated from the outer freezer and large refrigerator. The chambers are separated by air distribution pla...

AI Technical Summary

Problems solved by technology

[0005] In the process of implementing the above technical solution, the inventor found that if separate methods are used for the temperatures of the two refrigerating chambers, it is necessary to set air ducts in the cabinets of the refrigeration equipment and control the air volume. At this time, the air volume of the refrigeration equipment The road structure will be very complicated and will occupy more effective storage space in the box
