Notes: Test conditions for the unit are as follows:
Test conditions for nominal cooling capacity: inlet chilled water temperature at the application side 12°C; outlet chilled water temperature at
the application side 7°C; inlet cooling water temperature at the heat source side 30°C; outlet chilled water temperature at the heat source
side 35°C.
Test conditions for nominal heating capacity: inlet/outlet water temperature at the application side 40/-°C, and rated water flow at the
application side for nominal cooling; inlet/outlet water temperature at the heat source side 20/-°C, and rated water flow at the heat source
side for nominal cooling.
Test conditions for the heat recovery mode: inlet/outlet water temperature at the heat recovery side 40/45°C; inlet/outlet chilled water
temperature at the application side 12/-°C, and rated water flow at the application side for nominal cooling.
Test conditions for the water heater mode: inlet/outlet water temperature at the hot water side (application side) 50/-°C, and rated water
flow at the heat recovery side for heat recovery conditions; inlet/outlet water temperature at the heat source side (evaporation side) 20/-°C;
rated water flow at the heat source side for nominal cooling.
Switching between the cooling, heating, water heater, and heat recovery modes is implemented through an external valve connected to
the water system. The unit provides a interface for controlling the electric val
