Thus when vacuumizing, vacuum-pumping tube A is all connected vacuum pump with vacuum-pumping tube B, vacuum-pumping tube A vacuumizes box house, vacuum-pumping tube B vacuumizes heat insulation wall inside, vacuumized by vacuum-pumping tube B because heat insulation wall is not easily complete, Bidirectional gas pressure equalizing valve then can vacuumize the heat insulation wall around it; During release, gas enters casing through vacuum-pumping tube A, enters cabinet insulation wall through vacuum-pumping tube B, and carry out release because heat insulation wall is not easily complete by vacuum-pumping tube B, Bidirectional gas pressure equalizing valve then can carry out release to the heat insulation wall around it.
At least two passages are provided with in described Bidirectional gas pressure equalizing valve, wherein at least comprise one and pass into passage A and of gas by the inner channel B passing into gas to box house of heat insulation wall by box house to heat insulation wall inside, the air draft side of passage A is provided with the retaining valve A being passed into gas by box house to heat insulation wall inside, and the air draft side of channel B is provided with by the inner retaining valve B passing into gas to box house of heat insulation wall.In this enforcement, at least four passages are provided with in Bidirectional gas pressure equalizing valve, wherein there are two passage A and two channel B, the valve block of two retaining valve A is structure as a whole, thus two retaining valve A open or close simultaneously, the valve block of two retaining valve B is structure as a whole, thus two retaining valve B open simultaneously or close.
Be provided with circulating fan in described casing, the inlet side of circulating fan is disposed with evaporator and well heater along air flow direction.
The utility model has the following advantages:
The utility model can vacuumize and pressure discharge operations casing and heat insulation wall fast, and vacuumizing effect is good, overcomes heat insulation wall and vacuumizes halfway technical matters.
