Structure and principle:
1, by the air conditioning controller (user self), stainless steel heating water tank, a large negative ion humidifier. Beautiful appearance, good corrosion resistance.
2, temperature and humidity control instrument using the full integrated circuit digital display. It has high resolution, intuitive, convenient, high precision temperature control.
3, refrigeration system using air conditioner cooling, the temperature is reduced, the temperature is more stable.
4, heating using electric heating tube, high power heating tube can quickly raise the temperature to the set temperature, the use of gas generated by heating as a supplementary supplement.
5, humidification with advanced negative ion humidifier, it has superior and humidity automatic damping control for fog, ensure the indoor humidity is greater than or equal to 90%, compared with the widely used of spray humidification methods.
working principle:
When the indoor temperature is higher than the preset temperature thermostat control cooling, when the indoor humidity is lower than the set temperature, the thermostat control heating and humidifying system, repeated cycles of control the temperature and humidity within the set range of temperature and humidity. In order to avoid the thermostat relay frequent action, before delivery to the upper limit of 21 DEG C temperature controller, the lower limit of 19 DEG C, generally do not change.
