Note :

1)Cooling water temperature difference : 5.5° C constant

2)The table is used only for the purpose of presuming the capacity factor.

3)In DE model, the proper flow rate of hot water is required in case of heating mode. It requires proper consumption of hot water for required cooling capacity.

Adoption of the controlling circulation amount of the solution

In order to have a stable and effective operation under the wide range of hot water temperature given, absorbent pump driven by an inverter con- trols the optimal operation. This control is that hot water is effectively utilized to regenerate the refrigerant instead of heating up the solution not attributed to the cooling capacity at the partial load.

Features;

1.To shorten the start-up period in time.

2.To prevent the excessive heat rejection to the cooling water system.

Even if the heating amount of heat source becomes less, the unit can operate without fail by means of the procedure that the input is almost rejected to cooling water.

3.To improve COP at the partial load due to less input.
