Problems solved by technology

However, by denying passage through the exchanger, the system suffers a huge loss of efficiency because the energy associated with the polluted gas flow has not been used

Embodiment Construction

[0037] First, refer to figure 1 , shows a system 100 for air handling and air conditioning intended to provide cool air inside a building 200 preferably exposed to the hot and humid climate such as faced in Southeast Asia. Firstly, the system 100 comprises an enthalpy exchanger 2 , and a vapor compression refrigeration unit 4 interposed between this exchanger 2 and a building 200 . The control means are associated with the enthalpy exchanger 2 and possibly also with the vapor compression refrigeration unit 4 .

[0038] The enthalpy exchanger 2 is of conventional type, i.e. the first external air flow F1 and the second polluted air flow F2 from inside the building 200 are advantageously intended to pass through the enthalpy exchanger 2 in opposite directions, and the temperature and absolute The humidity is lower than the temperature and absolute humidity of the first external airflow F1.

[0039] Here, therefore, the enthalpy exchanger 2 ensures heat transfer between the pol...

Abstract

The invention relates to an air handling and air conditioning system (100) intended to provide fresh air to the interior of a volume (200), preferably a building, the system comprising at least one heat exchanger module with dual air flow allowing heat transfer and transfer of water vapour between the two air flows, the system being designed to be able to function in a mode for cooling the building, in which the two air flows are respectively comprised of an exterior air flow (F1) intended to be introduced into the building (200), and a cooler and drier stale air flow (F2) coming from the interior of the building. According to the invention, the system also comprises: means (20) for determining the relative humidity of the exterior air flow (F1) at the inlet to said heat exchanger module; and control means (6) configured to order a contribution of heat to the exterior air flow (F1) before its entry into the module if its relative humidity exceeds a predetermined value.

Description

technical field [0001] The present invention relates to the field of systems and methods for air treatment and air conditioning of buildings exposed, for example, to the hot and humid climates faced in South East Asia. However, other applications are also possible. For example, the invention is also applicable to air volumes involving drying problems involved in industrial applications such as the paper, food and microelectronics industries. [0002] More precisely, the invention relates to such a system equipped with a double air flow exchanger of the type enabling heat transfer and humidity / water vapor transfer between the two air flows passing through the exchanger. Such exchangers providing this dual transfer are often referred to as "total heat exchangers" or "enthalpy heat exchangers". [0003] Therefore, the invention is suitable for use in air treatment and air conditioning in buildings, preferably in housing and service industries. Thus, the exchanger ensures not o...
