Temperature balance method: Adopting static balance technology, namely the balance method of "cooling process without heating" and "heating process without cooling", it is different from the traditional dynamic balance technology of "cold and hot dynamic balance" of high-power refrigeration against high-power heating

Technique, that is, when the compressor needs to be turned on (the central controller automatically determines whether to turn on the compressor based on the working conditions)

The central controller adjusts the refrigerant flow rate according to different temperature points to control the cooling capacity, ensuring that the equipment operates in a relatively low power consumption state at all times

1 set of programming control software system, with the main functions as follows:

1. Temperature and humidity curve:

Paperless recording: Equipped with a built-in recording program, the controller's memory can store data for 24 hours and run for 300 days

Can easily generate temperature and humidity curve files automatically and convert them into XLS tables;

2. Perfect interface:

External USB port: can be directly connected to the printer, enabling local data to be printed online,

It is easy to export historical curves and other data using a USB port and a USB flash drive.

External LAN standard network interface: Without the need for dedicated server configuration, it can be easily connected to the company's computer local area network. A maximum of 16 devices can be connected and monitored, making it convenient and fast.

Equipped with RS-485 or RS232 standard communication interfaces, it can be controlled and managed online with computers Equipped with all Chinese upper computer software and providing communication protocols The upper computer acquisition program is written by the user, which includes protocols for opening temperature signals, various alarm and protection signals, and fault/shutdown status signals of the test box, in order to upload the temperature box temperature in real-time to the upper computer monitoring system. At the same time, a system fault and abnormal alarm digital node is provided. The upper computer monitoring system needs to collect the fault/shutdown signals of the test box, in order to achieve synchronous power-off between the sample and the temperature and humidity box through the main controller

3. Real time monitoring can achieve: simultaneously monitoring the operation status of 1-16 controllers, such as monitoring real-time data of controllers, signal point status, actual output status, etc

Support remote (external) fault diagnosis:

Technicians can leave ports through the network with the assistance of customers, open IE browser, enter the IP address of the controller, and enter the login interface to select operations or monitoring for diagnosis

4. Timing control

Two sets of timing output control interfaces, paired with 10-time control modes, can provide switch signal output according to program settings. Note that it is only a control signal, and the test power supply inside the box needs to be separately connected and equipped with a dedicated power supply system

5. Fault display
