Abstract
The invention relates to a process for cooling air-conditioning water used to air-condition a hospital building, comprising the steps of: (a) providing nitrogen in liquid form (LIN); (b) providing oxygen in liquid form (LOX); (c) providing air-conditioning water to be cooled; and (d) performing a heat exchange (4) between the air-conditioning water to be cooled and the nitrogen in liquid form (LIN) and/or the oxygen so as to cool the air-conditioning water and to vaporize the nitrogen and/or the oxygen and obtain nitrogen in gaseous form (GAN) and/or oxygen in gaseous form (GOX).
Claims7
A cooling facility (1) for cooling the air-conditioning water for air-conditioning at least one portion of a hospital building, comprising:
- a first water pipe (2) for air-conditioning water to be cooled,
- a nitrogen pipe (11) connected to a liquid nitrogen source (10) supplying nitrogen in liquid form (LIN),
- an oxygen pipe (21) connected to a liquid oxygen source (20) supplying oxygen in liquid form (LOX),
- heat exchanger (3) configured and adapted to perform a heat exchange (4) between the air-conditioning water to be cooled, provided by the first water pipe (2), and the liquid oxygen and/or the liquid nitrogen provided by said nitrogen pipe (11) and oxygen pipe (21), so as to cool the air-conditioning water and to vaporize the liquid oxygen and/or the liquid nitrogen and to thereby obtain nitrogen and/or oxygen in gaseous form,
- an atmospheric nitrogen vaporizer (19) and an atmospheric oxygen vaporizer (29) which are fluidically connected so as to be capable of being supplied, respectively, by the LIN source (10) and the oxygen source (20).
