Problems solved by technology

In addition, in order to exert the heating capacity commensurate with the heating load, there are almost always cases where the exhaust air only for ventilation is insufficient.
However, in the above-mentioned heating device, it is impossible to increase the air flow rate of the system (a) on the heat source side, causing insufficient heating capacity

Embodiment Construction

[0045] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0046] like figure 1 As shown, the air conditioner (10) of this embodiment is composed of a heat source system (20) and a utilization system (40).

[0047] The above-mentioned heat source system (20) is composed of a compressor (21), a heat exchanger (30), a moisture remover (22) and an expander (23) connected by pipelines in order to perform an air refrigeration cycle. Also, the heat source system (20) has a suction line (24) connected to the inlet side of the compressor (21), and a blowing line (25) connected to the outlet side of the expander (23). This suction line (24) is configured to have two branches at the first end, and supplies air to the above-mentioned compressor (21) from indoors and outdoors. At this time, exhaust air discharged from the room for ventilation is sent from the room to the compressor (21). Also, the blowing duct (25) is configured to guide lo...

Abstract

The compressor (21), the heat exchanger (30), the moisture remover (22), and the expander (23) are connected in sequence with pipelines to constitute a system of heat sources. The compressor (21) sucks in and compresses outdoor air and exhaust air for ventilation. The heat exchanger (30) for compressed air exchanges heat with the air for conditioning. Water vapor is removed from this compressed air by a moisture remover (22). After that, the compressed air is expanded by an expander (23), becomes low-temperature air, and is discharged to the outside. On the other hand, conditioning air is fed to the heat exchanger (30) through the inlet line (43). This air for conditioning is after mixing supply air for ventilation and indoor air. In the heat exchanger (30), the conditioning air is heated by heat exchange with the compressed air. Further, in the humidifying part (42), the conditioning air is humidified, and thereafter, the conditioning air is supplied to the room for heating.

Description

technical field [0001] The present invention relates to air conditioning units for heating using air circulation using air as a refrigerant, and in particular, to strategies for increasing heating capacity. Background technique [0002] Air cycle refrigerators using air as a refrigerant have long been known. For example, it is shown on pages 45 to 48 of "New Refrigeration and Air Conditioning Handbook, Fourth Edition, Basic Edition" published by the Japan Refrigeration Association. In addition, a heating device using an air-circulating refrigerator as a heat source for heating is shown in pages 16 to 21 of Air Conditioning Magazine (AIRAH JOURNAL, June 1997) issued by the Australian Association of Refrigeration, Air-Conditioning and Heating. Next, this heating device will be described. [0003] like image 3 As shown, the above-mentioned heating device is equipped with the system (a) of the heat source and the system (f) of the heat discharge. The system (a) in terms of t...
