Description
Technical Field
The utility model relates to a device of condensation is prevented.
Background
In a common supermarket project, the glass door of the display cabinet adopts a normally-on heating anti-condensation mode. The heating mode has the following defects:
1. the mode of normal electrification or contactor on-off is adopted, the heating wire always output at rated power wastes energy, and most importantly, the power consumption is large, and the consumption is monthly all the year round, so that the mode is not a small expenditure for supermarket operation.
2. The anti-condensation is that the heating wire generates heat, and the heat conduction is accomplished in glass door or the door frame and is got rid of the process of condensation, and glass door or door frame do not have the condensation always, if heat and have more heat to produce in the cupboard always to lead to increasing the freezer load and need continuously refrigerate.
SUMMERY OF THE UTILITY MODEL
The utility model provides a device of condensation is prevented according to solid state relay output control, including atmospheric control ware, external sensor, solid state relay and display regulator, wherein, atmospheric control ware and external sensor pass through the signal line and connect, and atmospheric control ware and solid state relay pass through the wire and connect, and atmospheric control ware passes through the wire and connects.
Preferably, the external sensor is a temperature and humidity sensor.
Preferably, a thyristor or a pulsed anti-dew control.
The utility model discloses the higher problem of consumption has effectively been solved.

Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.
The utility model discloses as shown in fig. 1, the device embodiment of preventing condensation according to solid state relay output control is provided, and whole device mainly comprises 1-temperature and humidity controller, 2-external sensor, 3-solid state relay, 4-demonstration regulator etc.. The temperature and humidity controller 1 is connected with the external sensor 2 through a signal line, the temperature and humidity controller 1 is connected with the solid-state relay through a lead, and the temperature and humidity controller is connected through a lead. All components are commercially available and the complete control system is available from the technical glass of andeoni (shanghai) ltd.
Further, the functional principle of each component is as follows:
a controller: and controlling the output of the solid-state relay by reading the data analysis of the external sensor.
An external sensor: and detecting the ambient temperature and ambient humidity values.
Solid-state relay: the output power level is adjusted by receiving the input signal level.
A display adjuster: when the parameters need to be adjusted or read.
Specification: the controller, external sensor, show the regulator, irregular check requirement.
The specification of the solid-state relay selects a corresponding model according to the load power.
The principle is as follows: and (3) condensation prevention process: after the temperature and humidity controller 1 is powered on, the external sensor 2 is detected to read the ambient temperature and the ambient humidity value, so that the controller calculates the dew point temperature of the environment, and the controller outputs signals to the solid-state relay 3 to continuously adjust the output power through the logical relation between the dew point temperature and the ambient temperature. Thereby realizing the intelligent control of the anti-condensation heating wire. The display regulator 4 can check the percentage value of the power used, the display environment temperature value and the display environment humidity value in real time.
The embodiment has the following advantages:
1. the heating logic is switched on and off by canceling normal power or always using rated power through a contactor, a contactless electronic switch with an isolation function is adopted, and intelligent control of a mechanical contact component is not needed in the switching process of which the switching speed can be from a few milliseconds to a few microseconds.
2. High control precision, long service life, energy and power saving and high safety factor.
3. The power of the anti-condensation heating wire can be adjusted in real time according to actual conditions.
4. Long service life, high reliability, high sensitivity, small control power, good electromagnetic compatibility, fast conversion, small battery interference, short circuit protection, overload protection, overheat protection and the like.
5. Because the low-power heating is continuously and stably carried out, the load of the display cabinet is reduced, the power consumption is saved, the prepayment cost of a customer is reduced, and the effect of saving energy is achieved.
The above description is only for the preferred embodiment of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
