Embodiment Construction

[0027] In order to facilitate the understanding of this application, the following will make a more comprehensive description of this application with reference to the relevant drawings. The drawings show preferred embodiments of the application. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of this application more thorough and comprehensive.

[0028] See figure 1 , A refrigerant detection method for a cooling machine, including: step S200, step S300, and step S400.

[0029] Step S200: Obtain the current pressure data of the condenser gas header of the cooling machine.

[0030] Specifically, the condenser is a kind of heat exchanger, which can convert gas or vapor into liquid, and transfer the heat in the tube to the air near the tube in a fast manner. The working process of the condenser is an ex...

Abstract

The invention relates to a cooler and a refrigerant detection method, device and system thereof. The current pressure data on a condenser gas collection main pipe of the cooler is acquired and analyzed, and then the pressure deviation value corresponding to the current pressure data is obtained according to a preset pressure database. When the pressure deviation value is greater than or equal to the preset deviation value, refrigerant leakage of the cooler at the moment is considered, and the alarm message about the refrigerant leakage is controlled and output right away, so that a user is timely informed that the refrigerant leakage risk of the cooler and can overhaul the cooler without delay. Through the scheme, as long as the current pressure data of the condenser gas collecting main pipe are detected to be greatly changed, the corresponding alarm message about refrigerant leakage can be output to inform the user, therefore, when refrigerant leakage occurs, the user can be informedin time, main parts of a machine tool can be effectively prevented from being damaged due to cold water temperature fluctuation, and the detection is highly reliable.

Description

Technical field [0001] This application relates to the field of refrigeration technology, in particular to a chiller and its refrigerant detection method, device, and system. Background technique [0002] Cooler is a kind of machine that achieves cooling effect through vapor compression or absorption cycle. It is generally used on matching machine tools to provide cold energy for the main parts of the machine tool and cool down the main parts of the machine tool to effectively protect the spindle of the machine tool. The main components ensure the normal operation of the machine tool. Therefore, it is particularly important to ensure the stable operation of the cooler when the machine tool is working. [0003] The abnormal situation of refrigerant leakage often occurs during the operation of the cooler. The traditional refrigerant detection method will report the low-pressure protection information only when the refrigerant leaks to a certain extent. Since it is impossible to kno...
