no. 1 Embodiment approach

[0085] Hereinafter, the present invention will be described in detail based on the drawings showing the embodiments. figure 1 is a schematic longitudinal sectional view of the air conditioner according to the first embodiment of the present invention, figure 2 is a plan view, image 3 is along figure 1 A cross-sectional view of the B-B line, Figure 4 It is a schematic side view of the air conditioner of the first embodiment seen from the inlet of the return air, Figure 5 It is a schematic diagram showing the structure of key parts.

[0086] The air conditioner according to the first embodiment is a heat pump type desiccant air conditioner, and includes a housing 6 in which a heat source side housing 9 having substantially the same shape is provided on a rectangular air supply side housing 8 . A heat pump A consisting of a compression-type first heat pump A1 and a compression-type second heat pump A2 is arranged in the housing 6 in the shape of a vertical cube; the heat ...

no. 2 Embodiment approach

[0095] The second embodiment will be described in detail below with reference to the drawings, Figure 6 is a schematic side view of an air conditioner according to a second embodiment of the present invention, Figure 7 is a plan view, Figure 8 It is a schematic diagram showing the structure of key parts.

[0096]The air conditioner according to the second embodiment has a casing 6 in which a square-shaped air supply-side casing portion 8 is provided on a heat source-side casing portion 9 having substantially the same shape. The heat source side case part 9 has: a heat source side outside air inlet 12 for introducing outside air into the heat source side case part 9, a heat source heat exchanger 7 (different from the first embodiment), and The compressor 10 composed of the compressor 10A and the second compressor 10B, the heat source side blower 4 for passing the outside air and the return air through the heat exchanger 7 for the heat source, and the exhaust air for exhaus...

no. 3 Embodiment approach

[0104] Next, the third embodiment will be described in detail with reference to the drawings. The air conditioner of the third embodiment is an air conditioner in which the return air processing heat exchanger 2 in the air conditioner of the first embodiment is omitted. The air conditioner of the third embodiment is arranged in a casing 6: a heat exchanger 1 for treating external air of a compression heat pump A capable of exchanging heat with external air and switching between cooling and heating; a humidifier 5 for humidifying external air; Air-supply-side blower 3 that mixes the return air with the outside air that has passed through the heat exchanger 1 for treating outside air and the humidifier 5 and supplies the air. The heat pump A includes at least an external air treatment heat exchanger 1 that performs different steps in an evaporation step and a condensation step, common heat source heat exchangers 7, 7, a first compressor 10 that compresses a circulating refrigera...

Abstract

The invention provides an air conditioner, which respectively treats the outer air load and the indoor load without needing additional energy for cooling and reheating the returned air so as to save energy resource and reduce the operating cost; the air conditioner only utilizing thermal pump without using cold warm water pipe coil to control the temperature and the humidity of the supplied air, thereby realizing the reduction of the equipment cost and the operating cost. The air conditioner of the invention comprises: a first thermal pump A1 which can switch the cooled / heated outer air treatment adopted heat exchanger 1, a second thermal pump A2 which can switch the cooled / heated returned air treatment adopted heat exchanger 2, a humidifier 5 which humidifies to the outer air, and an air supply side ventilator which mixes the returned air of the returned air treatment adopted heat exchanger and the outer air of the outer air treatment adopted heat exchanger and the humidifier and then supplies air; after the mixing the outer air and the returned air, the outer air load and the indoor load can be respectively treated without cooling or heating.

Description

technical field [0001] The invention relates to an air conditioner which processes external air and supplies air to a room. Background technique [0002] Conventionally, the so-called external air mixing type air conditioner (or air conditioning device) that mixes external air and return air mixes the external air from the outside and the return air from the room, and the mixed air (hereinafter referred to as the mixed air) ) for cooling, dehumidification, heating, etc. For example, during air conditioner operation in summer, air mixture is supercooled and dehumidified, and reheated (reheated) to control humidity to supply air to the room (for example, refer to Patent Documents 1 and 2). [0003] Since the air conditioner of this type cools and reheats the mixed gas, it must cool and reheat both the external air and the return air constituting the mixed gas, and there is a problem of increased operating costs. [0004] In addition, when the heat source water circuit is a 4...
