Technical Field
[0001] The invention relates to the technical field of raw material mixing equipment, and in particular to a multi-raw material mixing equipment for preparing refrigerant. Background Art
[0002] Refrigerants are media substances used to complete energy conversion in various heat engines. These substances usually increase power through reversible phase changes, such as refrigerants in refrigerators. Refrigerants absorb heat from the cooled object at low temperatures and transfer it to cooling water or air at higher temperatures.
[0003] Mixed refrigerants are refrigerant compositions formed by mixing two or more pure refrigerants in a certain proportion. They are designed to optimize the refrigeration cycle performance in specific applications, such as improving energy efficiency, widening the operating temperature range, and enhancing environmental protection characteristics. Mixed refrigerants can be divided into two categories: azeotropic mixed refrigerants and non-azeotropic mixed refrigerants according to the boiling points of their components. The current azeotropic mixed refrigerants include R407C, R410A, etc., which are widely used in air conditioning and heat pump systems.
[0004] The traditional refrigerant mixing method directly introduces multiple refrigerant raw materials into a mixing tank. The refrigerant mixing is prone to stratification, resulting in poor mixing effect and low mixing efficiency. Summary of the invention

[0035] The method of using the present invention:
[0036] First, it should be clear that the mixing device involved in the present invention is mainly used for the mixing operation of multiple liquid refrigerant raw materials. The present invention takes the mixing of two refrigerant raw materials (such as the mixing of R407C and R410A) as an example to explain its use method in detail. When the refrigerant raw materials need to be mixed, the following steps are followed:
[0037] S1, start the heater 310, and raise the working temperature of the heater 310 to a temperature that can efficiently distill the refrigerant raw material in the raw material tank, and the temperature needs to be adjusted based on the boiling point of the liquid refrigerant raw material as a reference standard;
[0038] S2, turning on the blower 320 and the heat transfer reversing valve 800 at the same time, opening the heat transfer reversing valve 800 to introduce heat into the upper part of the raw material tank, and realizing efficient, rapid and uniform distillation of the gaseous refrigerant in the raw material tank by allowing the hot air generated by the heater 310 to pass smoothly through the bottom and the upper part of the raw material tank at the same time;

The supercharger will pre-mix and pressurize the vaporized refrigerant passing through the serpentine pipe through the heat-conducting fins 312 and the serpentine pipe, so as to facilitate the speed and pressure of the refrigerant after it is sprayed through the spray pipe;
[0040] S4, turn on the cooler to lower the temperature in the cooling tank 600 to the temperature at which the mixed gaseous refrigerant is liquefied, and the gas mixed in the mixing tank 400 will enter the cooling tank 600 to be liquefied and then discharged;
[0041] The present invention can achieve preliminary mixing of refrigerants of various raw materials through the distillation mechanism 300 in cooperation with the mixing mechanism 500, and then perform efficient and rapid mixing operations, which greatly improves the mixing efficiency and mixing accuracy, and solves the problem that the traditional mixing method directly introduces various refrigerant raw materials into the mixing tank 400, and the mixing of the refrigerants is prone to stratification, resulting in poor mixing effect and low mixing efficiency.
