摘要： When in operation, devices for telecommunications installed in rooms generate a considerable amount of heat. This takes place continuously, and a maximum temperature must not be exceeded. In order to obtain reserve time for an air cooling system having a reserve time system with a guaranteed low temperature level of the liquid for the reserve time system, an evaporator (2) for the air cooling system is provided with a liquid circuit (2b) which is connected with a liquid tank (7). Liquid is circulated continuously through the evaporator with the liquid circuit, where it is cooled by the cooling medium for the air cooling system, at the same time as the inside air is cooled by the same evaporator. The continuous cooling and circulation of the liquid in the tank ensures that there is always the coldest possible liquid available when the ordinary cooling system is not working. In case of failure of the air cooling system, liquid is circulated by means of a liquid pump (6) from the tank via the evaporator provided with the liquid circuit, thus cooling the warm inside air. The heated liquid is returned to the tank. When the air cooling system is working again, it will start to fill the tank with cold liquid.
