Embodiment 1

[0078] A method for using a cavity with both convection and radiation functions installed on an indoor wall, including the following steps: Step (1), preliminary rapid temperature adjustment: turn on the DC brushless fan coil unit, and turn on the DC brushless Drive the motor to the highest speed, so that the centrifugal fan reaches the highest speed, and the wind pressure reaches about 60Pa, overcomes all the resistance of the control air valve, heat exchanger and micro-orifice plate (the resistance of these parts is about 30Pa), and maintains about 30Pa The residual pressure outside the cavity keeps the indoor convection and large heat exchange;

[0079] Step (2), when the indoor temperature is reached, the "initial adjustment" is completed, and the brushless DC motor starts to slow down slowly. The wind pressure is adjusted downward from 60Pa. While adjusting the wind pressure, if the room temperature can still be maintained, then continue to adjust downward until the wind ...

Embodiment 2

[0083] The present invention is also a method for using the cavity with convection and radiation functions installed on the indoor wall described in any one of the above solutions, including the following steps:

[0084] Step (1), turn on the DC brushless fan coil unit and set it to high-speed wind pressure, control the air valve to open, perform high-speed refrigeration cycle, strong dehumidification, 2 to 10 minutes; step (2), turn the DC brushless The brush-type fan coil unit is converted to low-speed wind pressure and heating cycle, the control air valve is closed, the temperature is raised slowly and slightly, and it runs for 20 to 60 minutes; step (3), repeat step (1) and step (2) repeatedly, and keep Suitable indoor temperature and humidity. The number of repetitions can be determined according to the set relative humidity.

[0085] The humidification system of the present invention can use a common humidifier to humidify the room.

Abstract

The invention relates to a cavity mounted on an indoor wall and provided with convection and radiation functions. The cavity comprises a cavity body, a direct-current brushless fan-coil unit and control air valves; the cavity body is mounted on the wall, windows and micropores are arranged on the cavity body, the windows are used for mounting the control air valves, and the micropores are distributed uniformly; the direct-current brushless fan-coil unit is mounted in the cavity body; and the control air valves are mounted at the windows on the cavity body. The cavity has the advantages that an indoor unit of a common air conditioner can be replaced by the cavity, the direct-current brushless fan-coil unit is arranged in the cavity body, and the control air valves are arranged on the cavity body, so that quick forced-convection heat transfer for temperature adjustment can be quickly implemented within short startup time; the micropores are uniformly distributed on the cavity body, so that the indoor temperature can be finely adjusted in a radiation manner; and the indoor temperature can be quickly increased or reduced by means of controlling starting of the direct-current brushless fan-coil unit, and can also be finely adjusted in the radiation manner, so that people are prevented from feeling uncomfortable due to a long-term forced-convection heat transfer mode.

Description

technical field [0001] The invention relates to a cavity and a use method, in particular to a cavity installed on an indoor wall with both convection and radiation functions and a use method. Background technique [0002] At present, ordinary air conditioners are used to control the indoor temperature, and the indoor units of the air conditioners all adopt the method of forced blowing and convection heat exchange, which brings a lot of inconvenience to people's lives, especially when resting at night, it is easy to feel blown. Make people catch a cold! [0003] Cold radiant air conditioners are relatively easier to solve the shortcomings of forced blowing and convective heat exchange than ordinary air conditioners at present, but the more mature technology in cold radiant air conditioners is: cold roof radiant air conditioners, which install radiant cooling sources on the back of the ceiling. In the above-mentioned mature technologies, a lot of capillary tubes are densely a...
