Hysys, the advantages of the water loop

Drawing on its specialist market experience, CIAT has extended this system solution with Hysys Office for office spaces, Hysys Hotel for hotel accommodation and Hysys Senior for retirement homes.
Packaged in this way, these solutions make the design and installation phases significantly easier. They also play an active role in obtaining and complying with certification, energy standards or environmental standards for the buildings in which they are fitted and lower their running costs.

Using water, the best heat transfer fluid, Hysys establishes itself as a real alternative to direct expansion systems by offering tangible benefits:   

Comfort :

Water ensures progressiveness and precise comfort for the occupants.

Energy efficiency :

the homogeneity and the thermal stability of water reduce the energy requirements for transferring heat.

Ecology :

no refrigerant on the premises, only a minimal amount in the heat pump outside the buildings' occupied spaces (–70% compared with direct expansion equipment).

With Hysys, the installation's TEWI (Total Equivalent Warming Impact) index is reduced by two-thirds

Simplicity:

Hysys does not require the services of refrigerant specialists during installation.

Highly modula:

Hysys adapts more easily to buildings' configurations and to developments in spaces and surface areas.

Competitiveness:

equipment in the water loop solution is less expensive to purchase and requires less maintenance than direct expansion systems.
