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 25°C; outlet chilled water temperature at the heat source
side 30°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 7/-°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) 7/-°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 valve.
■ 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 net weight in brackets indicates the weight of a dual-condenser heat recovery 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 EKWD032CRQRM/S, EKWD043CRQRM/S, EKWD032CRQVM/S, and EKWD043CRQVM/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.


More Efficient


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.

 

More Comfortable


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.

 

More Reliable


With modular design, the unit starts step by step, reducing the shock on the grid, and maintenance of a single unit does not affect running of other units. In addition, the unit provides multiple built-in security protection functions, and supports intelligent and centralized control, facilitating daily management.

 

More Energy Saving

 

The leading-edge shell design allows the unit to be installed in an outdoor space such as terrace and rooftop without the need of a dedicated room. The unit delivers a long lifecycle and runs for long. Units may be installed in batches according to project progress. One water system that works in multiple modes saves investment on other devices such as heating and hot water supply devices, thereby saving the energy.

 

Convenient Model Selection


The 32RT and 43RT basic modules support free combination of master units and slave units to
from 1 to 16 units, providing as many as 153 solutions for a cooling capacity as high as 688RT.

 

Easy Switching


The unit sends control signals to valves of the water system to easily switch between the water
source/geothermal heat pump mode, heat recovery mode, and water heater mode, meeting requirements for cooling, heating, and hot water around the clock.

 

Variable Water Flow Design


The unit easily implements variable primary flow pumping, which helps the central air conditioning system save energy by 30%.

 

Easy Transportation

 

The modular design allows transportation by using elevators and manual forklifts and eliminates the need for hoisting.


Easy Installation


The modular design allows units to be moved separately and assembled, facilitating installation work.
