The close pattern stated.
Here, the switching action of flow path switching valve 40 illustrates.
In Fig. 4, section g1, g2, g3 indicates that the operation interval of refrigeration cycle, section h1, h2 indicate stopping for refrigeration cycle
Only section.In each section of section g1, section g2 and section g3, compressor 19 is set to be operated, and switch flow channel switching valve
40 alternately to use dew eliminating tube 41 and dew eliminating tube 42.In Fig. 4, it in " opening and closing " of flow channel switching valve 40 action, opens anti-
Reveal the flow path of 41 side of pipe, and close the flow path of 42 side of dew eliminating tube, thus the refrigerant of main condenser 21 is in dew eliminating tube 41
Flowing, and the refrigerant being trapped in dew eliminating tube 42 is recycled to evaporator 20.Similarly, " closing in flow channel switching valve 40
Open " in action, the flow path of dew eliminating tube 41 side is closed, and open the flow path of 42 side of dew eliminating tube, the refrigerant of main condenser 21
It is flowed in dew eliminating tube 42, the refrigerant being trapped in dew eliminating tube 41 is recycled to evaporator 20.In addition, in flow channel switching valve 40
" closing " action in, close the flow path of dew eliminating tube 41 side, and close the flow path of 42 side of dew eliminating tube, stop in compressor 19
Section q1 and section q2 in, the refrigerant of main condenser 21 can be prevented to be flowed into evaporator 20 due to pressure difference.
In addition, in Fig. 4, using the temperature of the opening portion of the freezing chamber 18 warmed by dew eliminating tube 41 as representing temperature,
It is expressed as the surface temperature of shell.In addition, refrigeration cycle operation interval the dew eliminating tube originally used by each workspace
Between switch.Specifically, for example, as shown in figure 4, originally using dew eliminating tube 41 (time K) in section g1, in section originally g2 makes
With dew eliminating tube 42, usage time L.
In addition, the control time K using the dew eliminating tube 41 and time L using dew eliminating tube 42 carrys out the surface temperature of adjustment housings
Degree so that the average value of the surface temperature of the shell warmed by dew eliminating tube 41 becomes defined level.For example, based on by wet
The humidity regulation around freezer that degree sensor (not shown) detects uses the time K of dew eliminating tube 41 and uses dew eliminating tube 42
Time L ratio, it is higher in humidity, increase using dew eliminating tube 41 time K improve shell 12 surface temperature.
On the other hand, lower in humidity, increase the surface temperature that shell 12 is reduced using time L of dew eliminating tube 42, thus
Can take into account prevents moisture condensation and energy-saving.
Like this, by switching in the dew eliminating tube of the operation interval of refrigeration cycle originally used by each operation interval,
Time K and time L can be set as to the operation interval equal extent with refrigeration cycle, it can be by the operation interval of refrigeration cycle
In switching times be reduced to 1 degree.In addition, in order to cut down the switching times in the operation interval of refrigeration cycle, preferably
It can be adjusted with the same degree of operation interval of the sum of time K and time L and refrigeration cycle, or the mode bigger than operation interval
Section.In addition, in the startup of compressor 19, operation interval and stopping section based on immediate refrigeration cycle determine time K
It maintains to prevent condensation performance and makes the switching of dew eliminating tube thus, it is possible to coordinate the variation of the work ratio of refrigeration cycle with time L
Number is minimum limit.
