Problems solved by technology

[0006] In addition, since the indoor heat exchanger also becomes an evaporator during the dehumidification operation in which the air passing through the adsorption heat exchanger serving as the evaporator is supplied to the room, it also becomes the dehumidification and cooling operation for cooling at the same time, and the dehumidification operation is performed separately. If it is operated with cooling, one heat exchanger must be stopped, and the configuration becomes more complicated, which becomes a problem
In addition, since the indoor heat exchanger also serves as a condenser during the humidification operation in which the air passing through the adsorption heat exchanger serving as the condenser is supplied to the room, the humidification and heating operation for heating is also performed at the same time, and the humidification operation is performed separately. If it is operated with heating, one heat exchanger must be stopped, and the composition becomes more complicated, which becomes a problem
[0007] In this way, in the conventional air-conditioning system using the adsorption heat exchanger, the device configuration itself is a complex device that requires four heat exchangers, and on this basis, it becomes more complicated to cope with various operation modes, which is a problem.

Embodiment approach 1

Embodiment 1 of the present invention will be described. The air conditioning system of the present embodiment is composed of an air passage (60), a refrigerant circuit (50), and an adsorbent, and the air passage (60) includes a first passage (61) through which outdoor air flows to the room and indoor air flows to the outside. The second passage (62), the above-mentioned refrigerant circuit (50) performs a vapor compression refrigeration cycle, and the air-conditioning system (10 ) constituted. This air-conditioning system is a ventilating type air-conditioning system, and during operation, it takes in outdoor air (OA) and supplies it to the room, and at the same time takes in room air (RA) and discharges it to the outside.

[0070]

The air conditioner (10) described above will be described with reference to Fig. 1 and Fig. 2 . Still, as long as there is no special restriction, the words "upper", "lower", "left", "right", "front", "back", "front", and "inside" used in this...

other Embodiment approach

In the above embodiment, the air conditioner (10) may have the following configuration. Here, a modified example of the air conditioner (10) will be described.

[0146] -First modified example-

As shown in Fig. 10, an air conditioner (10) according to a first modification includes a refrigerant circuit (100) and two adsorption elements (111, 112). The refrigerant circuit (100) is a closed circuit connected in sequence by a compressor (101), a condenser (102), an expansion valve (103), and an evaporator (104). Refrigerant circulates in the refrigerant circuit (100) to perform a vapor compression refrigeration cycle. This refrigerant circuit (100) constitutes a heat source because at least the adsorption elements (111, 112) are heated. The first adsorption member (111) and the second adsorption member (112), including an adsorbent such as zeolite, constitute a first adsorption member and a second adsorption member, respectively. Also, a large number of air holes are formed i...

Abstract

Heat exchangers of a refrigerant circuit 50 are constructed of a first adsorption heat exchanger 51 and a second adsorption heat exchanger 52, both of which have an adsorbent supported thereon, and are constructed so as to be switched into an evaporator and a condenser. An air passage 60 is constructed so as to be switched into states in which air flowing from the outside of a room to the inside of the room and air flowing from the inside of the room to the outside of the room flow through either of the first adsorption heat exchanger 51 and the second adsorption heat exchanger 52. A dehumidifying operation mode and a humidifying operation mode can be performed by switching the flow of refrigerant and the flow of air at specified intervals, a cooling operation mode and a heating operation mode can be performed without switching the flow of refrigerant and the flow of air, and an ventilating operation mode can be performed by flowing air through the air passage 60 in a state where the refrigerant circuit 50 is stopped.

Description

technical field [0001] The present invention relates to an air conditioning system, in particular to condensers and evaporators (or equivalent heaters and coolers) using refrigerant circuits, and possible absorption of moisture in the air and release of moisture into the air Air-conditioning system composed of adsorbents. Background technique [0002] So far, as such an air-conditioning system, a refrigerant circuit having a vapor compression refrigeration cycle has been installed in addition to two air heat exchangers (outdoor heat exchanger and indoor heat exchanger) for heat exchange between refrigerant and air. Two adsorption heat exchangers (heat exchangers with adsorbent loaded on the fin surface of the air heat exchanger), an indoor heat exchanger is set in the indoor unit and two adsorption heat exchangers are set in the outdoor unit for outdoor heat exchange device (for example, refer to Patent Document 1). [0003] In this air conditioning system, the moisture in...
