The second way is to adopt electrical heating to heat up to reduce the relative humidity of air.Because this kind mode can not reduce airborne absolute moisture content, is the way of curing the symptoms, not the disease.And, when the room air absolute moisture content is very high, need just can make relative humidity reach requirement air heat to very high temperature.Like this, temperature index is difficult to again guarantee, while operating cost height, not energy-conservation.
The third mode is to adopt handpiece Water Chilling Units (can be air-cooled or water-cooled) associative list cooling coil to dehumidify, and reduces the absolute moisture content of air.Adopt electrical heating to realize atmosphere temperature rising then, finally meet the requirements of air condition.This mode can guarantee the state parameter that needs, but the condensation heat that handpiece Water Chilling Units produces directly drained, be not fully utilized, very not energy-conservation yet.
The 4th kind of mode is to add hot-air by water resource heat pump in conjunction with heat(ing) coil, realizes atmosphere temperature rising, reduces relative humidity.This mode is compared energy-conservation with the second way, but can not guarantee promptly that equally temperature guarantees humidity again, can not meet the demands fully.
