The refrigeration cycle of the constant temperature and humidity light incubator adopts the inverse card cycle system, which is composed of two isothermal processes and two adiabatic processes. The whole process is as follows: the refrigerant reduces the working pressure to a higher level through the heat insulation of the compressor, and the consumed power increases the temperature of the exhaust pipe. After that, the refrigerant conducts a heat exchanger with the surrounding materials through the isothermal process of the cooler, and sends heat energy to the surrounding materials. The rear refrigerant works through adiabatic deformation of the interception valve, and the refrigerant temperature decreases at this time.
The design of the refrigeration system uses kinetic energy control technology, which can not only ensure the normal operation of the refrigeration unit, but also reasonably and effectively adjust the energy consumption and power of the refrigeration system.
Select the balanced temperature control (bthc), and the automatic control system will finally realize the stable balance under the continuous operation of the refrigeration system according to the set temperature point and the PID automatic calculation and derived conclusion.
Low temperature incubator compressor does not start the inspection process:
The cooling components of the cell incubator include the power circuit controller, driver, protection device and the compressor itself. The failure of the compressor to start is related to the above four parts. In case of common failure at any part, Jingda instruments and equipment will teach you a set of escape methods. The manufacturer of the constant temperature incubator can more clearly grasp the common failure parts of the low temperature incubator according to the following inspection.
First, connect the switch power supply of the low-temperature incubator. When the indicator light is on, it indicates that there is working voltage. The main circuit is basically normal. Next, check the temperature control board to see if there is 220 working voltage sent to the compressor. If not, it indicates that the temperature control board is damaged. If yes, check the operation solenoid coil and operation resistor of the compressor. Overtemperature and overcurrent protector. There is no problem with the above inspection. It must be that the compressor of the intelligent constant temperature and humidity incubator is damaged and only needs to be replaced.
