In cold room Rf, the front of storeroom Ty is covered by door 2, easily flows into because the switch of door 2 makes extraneous air, and outside heat easily enters from the contact portion (seal Pk) of housing 1 and door 2.,, in storeroom Ty, front easily becomes high temperature compared with rear.Therefore, in cold room Rf, if drive cooling device 3, the air of high temperature is in the front side flow of storeroom Ty, and the air of low temperature flows at rear side.Thus, easily produce the air stream of rising in the front side of storeroom Ty, easily produce the air stream of decline at rear side.

In cold room Rf, by cooling device 3 being moved and carrying out heat exchange by evaporimeter 35, main part 41 ambient airs of cooling chamber 4 are cooled and produce cold air.Now, the air of the SPACE V a between wall body 410 (cooler) and the cold-storage member 6 of main part 41 downsides also cooling by wall body 410 (cooler) and produce cold air.And the cold air producing at the lower surface of wall body 410 (cooler) is low temperature and flowing downwards.And, owing to disposing cold-storage member 6 in the below of wall body 410 (cooler), so cold air contacts with cold-storage member 6.The cold air contacting with cold-storage member 6 absorbs heat (latent heat) from the latent heat cool storage material of cold-storage member 6, and to the endwall flow of cold-storage member 6.

In the time that cold air flows on the surface of cold-storage member 6, heat up by absorbing heat from cold-storage member 6, but be not warming up to mobile upward degree.And the cold air that absorbs heat from cold-storage member 6 flows to the more below of storeroom Ty from the end of cold-storage member 6.

In wall body 410 (cooler), below do not configure the cold air producing in the region (fringe region) of cold-storage member 6, do not contact with cold-storage member 6 but flow downwards.The cold air flowing along the surface of cold-storage member 6 and heat up with utilize wall body 410 (cooler) to produce and direct mobile cold air, at the interflow, outside of the end edge portion of cold-storage member 6, and flow towards the bottom of storeroom Ty.Therefore,, compared with the situation of cold-storage member 6 is not installed, the temperature of the cold air flowing down to storeroom Ty below is higher.

Thus, by configuration cold-storage member 6, can improve the temperature of the cold air flowing down in storeroom Ty.And, by changing the cold air that directly flows down from wall body 410 and the ratio at the mobile cold air in cold-storage member 6 surfaces, can adjust the temperature of the cold air flowing down to storeroom Ty below.

As changing the cold air that directly flows down from wall body 410 (cooler) and the method in the ratio of the mobile cold air in cold-storage member 6 surfaces, can enumerate the size that changes cold-storage member 6.

For example make cold-storage member 6 diminish, the amount (ratio) of the cold air not contacting with cold-storage member 6 in the cold air producing on wall body 410 (cooler) surface but flow down becomes many, flows and amount (ratio) step-down of the cold air that heats up on the surface of cold-storage member 6.

In addition, by changing material, the capacity of latent heat cool storage material of cold-storage member 6, the temperature of the cold air mobile on cold-storage member 6 surface be can change, thereby the cold air that directly flows down from wall body 410 (cooler) and the temperature at the mobile mixed cold air of cold air in cold-storage member 6 surfaces also can be changed.Thus, can adjust the cooling velocity of storeroom Ty.In addition, change the size in the gap between wall body 410 (cooler) and cold-storage member 6, and change the cold air that directly flows down from wall body 410 (cooler) and the ratio at the mobile cold air in cold-storage member 6 surfaces, thereby also can adjust the temperature of cold air, and adjust the cooling velocity of storeroom Ty.And, by adjusting the cooling velocity of storeroom Ty inside, can adjust the Temperature Distribution of storeroom Ty inside.In addition, when by cooling device 3, storeroom Ty being carried out when cooling, cold-storage member 6 plays a role as the padded coaming of heat.

In addition, a part for the cold air flowing downwards from the gap between cold-storage member 6 and storeroom Ty inwall flows along the upper surface of support 71, and remainder flows towards the below of support 71.The cold air mobile along support 71 upper surfaces flows towards face side, by the article that are placed on support 71 upper surfaces are carried out to the cooling air that becomes intensification.The air heating up collaborates with the air stream of the rising producing in front surface side, and flows upward.Owing to also producing same cold air and air stream on support 72, so omitted detailed description.

And the cold air flowing downwards from the gap between end and the storeroom Ty inwall of support 72 rear sides flows into containing box body 8.Because the rear side of storage casing 8 tilts towards the mode of front side with below, so cold air flows along above-mentioned incline direction.And cold air flows towards front in storage casing 8, by the article that are accommodated in storage casing 8 are carried out to the cooling air that becomes intensification.And the air of intensification flows upward in the front side of storeroom Ty.
