Abstract

A cold storage installation having a part thereof which is available for rapid freezing consists of a number of open compartments which are disposed one following the other and intercommunicating. Certain consecutive compartments are associated with means such as fans for creating air circulation conditions necessary for their utilization as freezing spaces. These consecutive compartments are adapted to be covered in longitudinally, possibly by fixed walls and movable elements associated with the compartments or possibly in part at least by elements on pallets to be located in the compartments. The freezing compartments are preferably upstream of the refrigerating equipment which may be located in an upper passage. The whole array of compartments is preferably provided with corridors, air circulation passages being located parallel to the corridors and transversely at the ends of the corridors.

Dependent claims

A freezing and cold storage installation comprising in combination:

an elongated room, the sides of which are provided with thermal insulation;
a plurality of longitudinal racks extending over a major part of the length of said room between the end portions thereof, said racks each being provided with a series of superimposed horizontal rows of compartments adapted to receive goods to be frozen and stored, the compartments of each said rows communicating in a longitudinal direction with one another and with said end portions of said room, the racks having longitudinal corridors therebetween for enabling goods to be introduced into and removed from said compartments;
a longitudinal duct substantially parallel to said rows and communicating with said end portions of said room;
means in said duct for circulating air from one end portion of said room to the other end portion of said room and for cooling said air;
and means for laterally enclosing a series of adjacent compartments in a row and building therewith a tunnel which communicates with one of said end portions of said room and with a said longitudinal duct, whereby air circulation conditions are created within said tunnel for enabling it to be used as a freezing space.
