Embodiment Construction

[0106] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0107] Basic data debugging test test method:

[0108] Such as figure 1 Shown:

[0109] 1. Test ambient temperature: control the temperature at 5-45°C respectively;

[0110] 2. Test environment humidity: control the humidity at 20%-100% respectively.

[0111] 3. Point layout: point distribution in each storage room (according to the American standard energy consumption test requirements), five points are equally spaced on the surface of the horizontal and vertical beams;

[0112] 4. Gear position: strong gear in the refrigerator / high gear in the freezer;

[0113] 5. Heating wire test conditions:

[0114] a. Vertical beam: 0W to 25W, increase by 1W each time (the power can also be increased in other increments); ...

Abstract

The invention relates to a method and a system for preventing condensation, wherein the heating power of a heater strip and the corresponding temperature and humidity information are stored into a foundation database to construct a condensation-prevention foundation database; the method for preventing condensation comprises the following steps: setting up the foundation database of temperature, humidity and heating power, and controlling the heater strip to heat at the corresponding power according to the control power in the foundation database corresponding with the specific temperature andhumidity; and the system for preventing condensation comprises a temperature sensor, a humidity sensor, a heating device and a master control board, wherein the master control board is provided with the foundation database. Thus, at the specific temperature and humidity, the heater strip works at the control power corresponding with the temperature and humidity at the same time in the foundation database, the energy consumption can be reduced effectively, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the anti-condensation field of cooling and freezing devices, in particular to an anti-condensation method and system for refrigerators, freezers and cold storage rooms. Background technique [0002] When the temperature difference between the inside and outside of the refrigerator is large, condensation will occur on the surface of the refrigerator. In order to solve this problem, U.S. Patent Document US7340907 provides a solution, through the sensing module to sense the air state near the sensor connected to the refrigeration equipment and input this information into the control module; the control module receives the input of the sensing module, and the input and The built-in value is compared. If the input is different from the preset value, an output indicating the difference between the input and the preset value is generated. This output is expressed as a percentage of 0-100. The control module continuously updates this...
