Abstract: An air condition installation adjustable in storing and dispensing coolness includes a coolant circulating course, an unfreezable liquid circulating course, one or more cool-storing tanks and a blower. The cool-storing tank consists of a cylindrical hollow tank filled with a cool-storing liquid, a tubular body housed in the tank, and two separated chambers in the front portion of the tank. The tubular body has an inlet and an outlet respectively communicate with the separated chambers and then with the unfreezable liquid circulating course so as to permit the unfreezable liquid exchange heat with the cool-storing liquid. Each cool-storing tank is of small dimensions to save space for installing, having high heat effect, able to be made to have plural small units.

Abstract: A cooling device which includes a conveyer belt to carry food products thereinto is provided with improvements in which a spraying device for spraying a cold salt solution onto the belt includes a first and second spraying unit provided above and below the conveyer belt so that a salt solution can be sprayed both directly onto the food products and onto the bottom side of the belt when the food products are covered or packaged, or sprayed onto the bottom side of the belt only when the food products are not covered or packaged. A secondary cooling unit operating with a cooling medium coming from an evaporator of the cooling device includes a tray-like member divided by a heat transfer plate into an upper chamber for receiving the salt solution after being sprayed and a lower chamber for receiving the cooling medium.
