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.
■ The water main of the assembled unit needs to be made and mounted on site, and the diameter needs to comply with the design
specification.
■ The attached Y-shaped filter must be mounted at the water inlet of the evaporator of each unit.
■ The cooling water and chilled water of the unit must be softened to avoid scaling in the heat exchanger.
■ The water pressure drop of the unit does not include resistance of any external water pipe or component.
■ Basic modules of the assembled unit are EKWD032CRSQM/SM/S and EKWD043CRSQM/SM/S. A unit may be formed by modules of the
same model or different models.
■ Product specifications are subject to change due to upgrade without further notice.

Decription

1, The modular water source/geothermal unit supports applications in all conditions and can switch between multiple modes to fully meet user needs for cooling, heating, and hot water. With an innovative water system, the energy-saving unit delivers an EER as high as 5.7, provides higher energy efficiency when working at a partial workload, and saves energy by 50% compared with other systems after operation in a year.

2, The unit is designed with a comprehensive water system and consists of efficient components carefully selected and designed for a low operation noise. The unit supports fuzzy volume regulation for a narrow range of temperature changes and quickly reaches the set temperature.                        In addition, the unit provides hot water at a set temperature as high as 55°C quickly and steadily to meet requirements for comfortable hot water in all places..

3 With modular design, the
