Applications for partial (DS) and total (RC100) recovery and DHW production
Overview
Condensation heat in a chiller is usually disposed of in the air; it can be recovered intelligently by means of heat recovery, which may be partial (DS) or
recovers all the condensation heat that would otherwise be lost.
In the case of a reversible heat pump, partial recovery (DS) and total recovery (RC100) can also run in winter mode. In the former case, the partial
recovery (DS) deducts a rate from the heat production in the main heat exchanger, whereas, in the latter case of total recovery, the heat production is
an alternative to that of the main heat exchanger.
Below is indicative information. The provided diagrams are not complete and are used only to provide guidelines that allow a better use of the unit.

Chiller
With this type of system, the main hydraulic circuit of the chiller is connected to the user and produces cold water for air conditioning. The unit can be
set-up as a pump or pump and storage tank as alternative to the traditional solution seen installed in the system. The desuperheater (DS), with which
the machine can be supplied, will be connected by means of a technical water storage tank and external pump for DHW or to the system to produce hot
water for the post-heating coils of the CTA or other applications. RC100 total recovery, as an alternative to DS, can be used in the same applications,
Should the unit be a reversible heat pump, summer operation is the same as the aforementioned situation of the chiller. Instead, with winter operation,
the user has DHW produced from the heat pump. If the unit is equipped with a DS desuperheater, this can be also active in winter mode. However, in
this case, this value is deducted from the portion of heat from the hot water produced from the main heat exchanger.
The air conditioning and the production of domestic hot water in a 2-pipe system is a typical application in hotels, hospitals, gyms and hospitality struc-
tures in general.
