These devices are mainly used in commercial and industrial applications for the purpose of prepare the cooling water, which later on, through distribution pipelines and convectors, cool the room. Recently, because of the rational use of energy, we use devices that acts as large heat pumps. With these devices we can cool the room in the summer and simultaneously prepare hot water.
With these systems, it is a direct evaporation of the refrigerant at the point where we want to cool the space or process. As opposed to cooling units in this process of cooling or heating, medium such as water or glycol are not used. VRV allows the assembly of different power packs, possible are also additional extensions.
