Embodiment 1

[0037] Such as figure 1As shown, an intelligent maintenance management system for refrigeration equipment of the present invention includes an air-conditioning system 1, a database 6 and an intelligent terminal 7. The high and low pressure ends of the air-conditioning system 1 are connected to the intelligent valve 2, and the intelligent valve 2 has an electric Three-way valve 23, high-pressure passage 21 and low-pressure passage 22, high-pressure passage 21 communicates with the high-pressure end of air-conditioning system 1, low-pressure passage 22 communicates with the low-pressure end of air-conditioning system 1, and the other end of high-pressure passage 21 and low-pressure passage 22 are connected to the motor One port of the three-way valve 23, the other two ports of the electric three-way valve 23 are respectively connected to the vacuum pump 3 and the recovery machine 4 (or filling machine 5), and the output end of the recovery machine 4 is connected to the refrigeran...

Embodiment 2

[0052] The smart valve 2 is connected to the vacuum pump 3 and the filling machine 5 , and the refrigerant filling storage tank 9 is placed on the electronic scale 10 . When the refrigerant filling operation is performed on the air-conditioning system 1, at the beginning of the operation, the pipeline between the filling machine 5 and the air-conditioning system 1 changes continuously at a constant speed from the closed state to the fully open state, and it takes 3 to 3 hours to fully open the state. 5 seconds. When the refrigerant filling of the air conditioning system 1 is nearing the end, the pipes of the filling machine 5 and the air conditioning system 1 change from the fully open state to the closed state at a continuous constant speed, and the time to the fully closed state is 0.5 to 1 second. All the other parts are identical to Example 1.

Abstract

The invention discloses a refrigeration equipment maintenance management system, provides an intelligent refrigeration equipment maintenance management system and a maintenance management method, which are time-saving and labor-saving in operation, capable of realizing whole-process automatic identification control, safe and reliable, and solves the technical problems that in the prior art, operation is performed by manual experience, time and labor are wasted, and the safety problem is easily caused by misoperation or mistakes, so that maintenance quality cannot be ensured. The system comprises an intelligent valve connected with an air conditioning system, a vacuum pump, a recycling machine and a filling machine, a database storing information of air conditioning systems of a plurality of models, and an intelligent terminal, wherein the intelligent terminal collects the information of the air conditioning systems, maintenance index information of the air conditioning systems is called from the database and compared with pressure information of the air conditioning systems, and an access state of the intelligent valve is controlled according to a comparison result.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to an intelligent maintenance management system and maintenance management method for refrigeration equipment that saves time and effort in operation, fully automatic identification and control, and is safe and reliable. Background technique [0002] Air-conditioning systems are widely used in refrigeration systems, HVAC, and household air-conditioning to meet people’s cooling and heating needs. The maintenance of air-conditioning systems generally includes three major steps: refrigerant recovery, system vacuuming, and refrigerant filling. The entire operation The process is usually carried out manually step by step based on the experience of the operator, but the skills of the current installation and maintenance operators are often taught by the experience of the master, such as how much time is needed for vacuuming, how much vacuum should be pumped, and how much refrigeration should be a...
