Abstract
A switch cabinet arrangement and method with at least one IT rack or switch cabinet housing and with at least one cooling device, which has an air-liquid heat exchanger for cooling components accommodated in the IT rack or switch cabinet housing with cooled air, wherein the air-liquid heat exchanger includes a first flow for cooled liquid and a first return for heated liquid, wherein the cooling device includes a liquid-liquid heat exchanger, to the second flow of which the first return of the air-liquid heat exchanger is connected.
Claims8
A switch cabinet arrangement comprising at least one IT rack or switch cabinet housing through which air is passed for cooling components accommodated in the IT rack or switch cabinet housing, comprising wherein an air-liquid heat exchanger circuit is charged by the air and a liquid passing through the air-liquid heat exchanger is heated;
- a liquid-liquid heat exchanger having fluid passing through it, the heated liquid from the air-liquid heat exchanger being coupled to the liquid-liquid heat exchanger, with the liquid passing through the liquid-liquid heat exchanger having a boiling point lower than the boiling point of the heated liquid from the air-liquid heat exchanger under standard conditions.
A method for air conditioning a switch cabinet arrangement, comprising:
- Subjecting components accommodated in an IT rack or a Switch cabinet housing of the switch cabinet arrangement to air, whereby the air is heated,
- Passing the heated air through a first air-liquid heat exchanger, cooling the air and heating a second liquid passed through the first air-liquid heat exchanger, and
- Passing the heated second liquid through a liquid-liquid heat exchanger, wherein a first liquid passed through the liquid-liquid heat exchanger of a liquid cooling of the components having a boiling point lower than the boiling point of the second liquid under standard conditions is cooled and the first heated liquid is further heated.
