Embodiment 1

[0023] figure 1 It is a structural schematic diagram of the fresh air all-in-one machine in Embodiment 1 of the present invention. refer to figure 1 , this embodiment provides an all-in-one fresh air machine for adjusting the air in the room N. The fresh air all-in-one machine includes: an outdoor air inlet duct 110 , an outdoor refrigerant circuit, an outdoor airflow drive device 130 , an air supply duct 140 and a fresh air inlet 150 . The fresh air all-in-one machine preferably also includes a filter device (not shown in the figure). In this embodiment, the indoor refers to a relatively independent space, and the outdoor refers to another independent space relative to the indoor. In this embodiment, the all-in-one fresh air machine is located outdoors, and the air flowing through the all-in-one fresh air machine is discharged into the room through the air supply duct.

[0024] One end of the air inlet pipe 110 communicates with the outdoor air, and the other end communic...

Embodiment 2

[0045] figure 2 It is a structural schematic diagram of the fresh air all-in-one machine in Embodiment 2 of the present invention. refer to figure 2 , this embodiment provides an all-in-one fresh air machine for adjusting the air in the room N. The fresh air all-in-one machine includes: an outdoor air inlet pipe, an outdoor refrigerant circuit, an outdoor airflow drive device 230 , an air supply pipe 240 and a fresh air inlet 250 . The fresh air all-in-one machine preferably also includes a filtering device.

[0046] The difference between the all-in-one fresh air machine in this embodiment and the all-in-one fresh air machine in Embodiment 1 is that the refrigerant circuit in this embodiment does not include a four-way valve for cooling the air passing through the refrigerant circuit. The refrigerant circuit includes a compressor 222, a first heat exchanger 223, a second heat exchanger 224, a refrigerant and a throttling element.

Abstract

The invention provides a fresh air all-in-one machine which is used for adjusting indoor air. The fresh air all-in-one machine comprises an air inlet pipeline, a refrigerant circuit located outdoors,and an airflow drive device and an air feeding pipeline located outdoors, wherein one end of the air inlet pipeline communicates with outdoor air; the other end of the air inlet pipeline communicateswith the refrigerant circuit; one end of the air feeding pipeline communicates with the refrigerant circuit; the other end of the air feeding pipeline communicates with the indoor air; the airflow drive device is used for driving air in the refrigerant circuit to flow, so that the air in the refrigerant circuit flows from the other end of the air inlet pipeline to the other end of the air feedingpipeline; and the refrigerant circuit is used for adjusting the temperature of the air in the refrigerant circuit. The fresh air all-in-one machine has the advantages of integrated arrangement, convenience in installation, energy conservation and low noise.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a fresh air integrated machine. Background technique [0002] In the current field of fresh air systems, most of them use full heat exchange fresh air systems, which mainly rely on the temperature difference between indoor and outdoor environments to perform a certain limit of energy exchange and heat recovery. The full heat exchange fresh air system needs to be used together with the air conditioner in the room. In summer, the indoor air conditioner is turned on, the temperature is relatively low, and the outdoor temperature is relatively high. Through the total heat exchange system, a part of the indoor air with a relatively low temperature is exchanged with the fresh air with a relatively high temperature introduced from the outside. In this case, The fresh air introduced from the outside has been cooled to a certain extent, and then sent to the user's room for fresh...
