15.2 COLD WATER PRODUCTION (SUMMER MODE)
A minimum temperature of 5°C is allowed at the evaporator outlet: for lower temperatures, contact the Technical Department. In
this case contact our technical department to study the feasibility and assess the changes to be made according to demands. A
maximum temperature of 25°C can be maintained at the evaporator outlet in steady-state operation.
15.3 HOT WATER PRODUCTION (WINTER MODE)
When the system has reached steady state, the water inlet temperature must not drop below 25°C: lower values, not due to
transient phases or reaching steady-state, can cause system failures and could possibly break the compressor. The maximum
outlet water temperature must not exceed 60°C.
There could be failures to the regular operation of the unit or, in more critical cases, the safety devices could be triggered due to
temperatures higher than those indicated, especially if coupled with reduced water flow rates.
15.4 AMBIENT AIR TEMPERATURE AND SUMMARISED TABLE
The units are designed and built to operate in summer mode, with condensation control, at outdoor air temperatures between -
10°C and +46°C. In heat pump mode, the allowed temperature range of the outdoor air is from-20°C to +40°C depending on the
outlet water temperature as shown in the table below.
Operating limits
Minimum -10°C Maximum +46°C
Minimum +5°C Maximum +25°C
Minimum -20°C Maximum +30°C
Minimum +25°C Maximum +60°C
Heat pump mode for domestic hot water
Room temperature with water at maximum 39°C
Minimum -20°C Maximum +40°C
Room temperature with water at maximum 55°C
Minimum -10°C Maximum +35°C
Minimum +25°C Maximum +60°C
The following are the graphical operating limits for air-conditioning and domestic hot water production.
