Embodiment 1

[0052]A new fan control method according to an embodiment of the present invention, such asfigure 1 As shown, the fresh air blower control method is implemented by the following fresh air blower structure, which includes the intake air fan Fan1, the exhaust air fan Fan2, and the circulation adjustment part 4;

[0053]The circulation regulating part 4 includes an evaporator E, a compressor 11, a first condenser C2, a first expansion valve 14, a first condenser C1, and a second expansion valve 15, which are connected in sequence, and the second expansion valve 15 is also connected to the evaporator. E connection;

[0054]The inlet fan Fan1 is used to make the outdoor air flow through the evaporator E and the first condenser C1 in sequence and enter the room;

[0055]The exhaust fan Fan2 is used to make the indoor air flow through the first condenser C2 and discharge it;

[0056]The circulation regulating part 4 also includes a bypass flow path 18 provided with a bypass valve 17, and the bypass fl...

Embodiment 2

[0090]Compared with Embodiment 1, in this embodiment, the novel fresh air blower structure also includes a preliminary adjustment device 3, and outdoor air flows through the preliminary adjustment device 3, the evaporator E, and the first condenser C1 into the room in sequence;

[0091]The preliminary adjustment device 3 is used for preliminary temperature adjustment of outdoor air.

[0092]The initial adjustment device 3 includes a fin coil and a coil valve 19, and the coil valve 19 is used to control the circulation of the temperature medium in the fin coil so as to achieve preliminary cooling or heating of outdoor air.

[0093]A temperature sensor 20 is provided between the fin coil and the coil valve 19.

[0094]Specifically, the third sensor TH-F1 monitors the humidity and temperature of the outdoor intake air, and the controller 5 controls the inflow of the medium by controlling the coil valve 19 according to the data detected by the sensor and the data of the medium temperature detected ...

Abstract

The invention discloses a control method for a fresh air ventilator, and relates to the technical field of radiant panels. The control method is implemented through the following structure of the fresh air ventilator, the fresh air ventilator structurally comprises an air inlet draught fan, an air exhaust draught fan and a circulation adjusting part, and further comprises a preliminary adjustmentdevice, a fresh air valve D1, a recovery air valve D2, a recovery air valve D3 and an excessive heat dissipation air valve D4. The control method comprises the following steps that in a fresh air dehumidification mode, the fresh air valve D1, the recovery air valve D3 and the excessive heat dissipation air valve D4 are opened, the recovery air valve D2 is closed, and meanwhile, a compressor is started; and then the preliminary adjustment device and a second condenser are adjusted to enable the temperature value of an air outlet to be a preset temperature value F2. According to the control method, effective adjustment of the humidity and the temperature is realized, multiple working modes can be achieved by arranging the preliminary adjustment device, and different use requirements under different season conditions can be met.

Description

Technical field[0001]The invention relates to the technical field of fresh air blowers, in particular to a method for controlling fresh air blowers.Background technique[0002]In the field of indoor air conditioning and fresh air treatment, there are many devices on the market; for example, dehumidifying cold air is provided through fan coils or separators to adjust indoor temperature. These devices are guided by indoor thermostats, and they provide cold air without controlling humidity. To a minimum; in addition, these devices circulate indoor air without any fresh air entering. Other fresh air treatment devices or ventilation devices can provide fresh dehumidified air to the indoor environment, but cannot control the temperature or humidity of the air; the above-mentioned existing technologies are all Can not meet people's requirements for air temperature and humidity, comfort is low, and the efficiency of new fans is not high.Summary of the invention[0003]1. Technical problems to b...
