Background:

Speaking of freon, I believe everyone is familiar with it. It is a commonly used refrigerant. It is a colorless gas or volatile liquid form at room temperature. Freon is a working substance that circulates continuously in the refrigeration system and changes its state to achieve refrigeration. It can be detected by freon gas detector.

The refrigerant freon absorbs heat in the evaporator through the heat of the cooling medium (water or air, etc.) and transfers the heat to the surrounding air or water in the condenser to produce condensation. CFCS with different chemical composition and structure have different thermal properties. Some can be used in high temperature, and some can be used in medium and low temperature chillers to meet different refrigeration temperature requirements. In addition to being used as refrigerant, freon is also widely used as foaming agent, cleaning agent and so on. It also appears in household appliances, automobiles, fire fighting equipment and other fields.

Freon is almost completely insoluble with water, and its solubility in water is very low. It is generally soluble in chilled oil, but at high temperatures freon will break down from the chilled oil. Therefore, there are heaters in the fuel tanks of large coolers to keep them at a temperature to prevent the dissolution of freon.

Air conditioning and refrigerator bring great convenience to people and enhance people's comfort in life. However, the CFCS they use have wreaked havoc on the industry. First, the CLS in refrigerants cause persistent damage to the ozone layer, and second, their potential impact on the greenhouse effect.

Introduction:

Freon will destroy the ozone layer, produce greenhouse effect, so as to destroy the ecological balance of the environment, resulting in a series of environmental hazards. To prevent freon gas leaks, it is usually necessary to use freon gas detectors for real-time monitoring. JXCT industrial production network learned that freon gas detector and multi-channel gas sensor alarm controller used together, intelligent to achieve real-time detection of freon leakage concentration, and connected to the external Internet for remote control, in order to avoid gas leakage harm.

JXCT's FREon sensors are extremely sensitive to refrigerants used in air conditioners and refrigerators such as R-134A, R-404A, R-407C and R-410. There are gas cooling holes on the cap and base for heat dissipation, which is very suitable for portable gas detector.

Product features:

High sensitivity to R-134A;

Long life, low power consumption;

The late circuit is simple;

Ceramic base, strong resistance to environment

In addition, the Freon sensor for refrigerant gas detection can also be used in the Freon gas detector. Its sensor consists of an integrated heater and a tin oxide (SnO 2) semiconductor on an alumina substrate. When the detected gas exists in the air, the higher the concentration of the gas, the higher the conductivity of the sensor will be. Using a simple circuit, changes in conductivity can be converted into an output signal corresponding to the concentration of the gas.
