Problems solved by technology

[0008] 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
[0009] 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

[0101] 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.

[0102]

[0103] refer to figure 1 , Fig. 2 illustrates the above-mentioned air conditioner (10). Still, as long as there is no special restriction, the words "upper", "lower", "left", "right", "front", "back", "front", and "inside" used in thi...

other Embodiment approach

[0200] 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.

[0201] -First modified example-

[0202] 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 ho...

Abstract

First and second adsorption heat exchangers (51, 52) where adsorption agent is carried are used as heat exchangers of a refrigeration circuit (50), and switching over of an evaporator and a condenser is made possible. An air channel (60) is constructed so that it can be switched over regardless of through which one of the first and second adsorption heat exchangers (51, 52) air from outdoor to indoor and air from indoor to outdoor flows. Further, the following operation modes are made possible: a dehumidifying mode and a humidifying mode where the flow of refrigerant and the flow of air are switched over for each predetermined time period, a cooling operation mode and a heating mode where the flow of refrigerant and the flow of air are not switched over, and a ventilation operation mode where air is conducted through the air channel (60) with the refrigerant circuit (50) closed.

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...
