Control method for PTC humidification of constant temperature and humidity chamber

Abstract

The invention relates to a constant temperature and humidity chamber PTC humidification control method, a constant temperature and humidity chamber comprises a control module, a humidity detection circuit module, a water temperature detection circuit module, a first circuit output module, a second circuit output module, a current acquisition circuit module, a PTC humidification device and a peristaltic pump device, and the peristaltic pump device is connected to the PTC humidification device. The control method comprises the steps that the environment humidity in the constant temperature and humidity box is collected through a humidity detection circuit module, and a humidity electric signal is output to a control module; the water temperature detection circuit module detects the water inlet temperature of a water source and outputs a water temperature electric signal to the control module; the current acquisition circuit module performs mutual inductance detection to acquire the current temperature of the PTC humidifying device and outputs a temperature electric signal to the control module; the control module determines the output duration of the second circuit output module based on the humidity electric signal, the water temperature electric signal and the temperature electric signal and controls the peristaltic pump device to be started when the temperature electric signal reaches a temperature threshold value. The air conditioner is small in water consumption and fast in humidification.

Description

technical field [0001] The invention relates to the technical field of culture equipment, in particular to a control method for PTC humidification in a constant temperature and humidity box. Background technique [0002] The constant temperature and humidity box refers to a box device with controllable air temperature and humidity in the corresponding closed space, which is mainly used for culturing microorganisms, plants and animal cells. The constant temperature and humidity box has a two-way temperature and humidity adjustment system for refrigeration and heating, dehumidification and humidification. It is the basic experimental equipment for scientific research departments such as biology, agriculture, medicine, and environmental protection and major universities. The whole box of the constant temperature and humidity box has a good insulation ability against the cold and heat of the outside world, and the temperature and humidity in the box can be controlled near the ex...

AI Technical Summary

Problems solved by technology

The humidification of the humidification plate is too slow and it is difficult to control accurately, so the humidification method of the constant temperature and humidity box needs to be improved
