Intelligent double vortex tube cooling and heating system

Abstract

The invention discloses an intelligent double vortex tube refrigeration and heating system, which is mainly composed of a flow regulating valve, a main vortex tube, an auxiliary vortex tube, an intake valve, a main refrigeration coefficient control valve, an auxiliary refrigeration coefficient control valve, and a hot air flow temperature sensor. , cold air flow temperature sensor and controller, the controller adjusts and controls the main refrigeration coefficient control valve and the auxiliary refrigeration coefficient control valve according to the temperature information; the controller opens or closes the intake valve according to the flow opening data, so that the auxiliary vortex tube Start or stop a job. The invention makes full use of the characteristics of vortex tube cooling and heating, and the cooling capacity is the same as the heating capacity, realizes the precise control of the vortex tube cooling and heating air temperature through the control system, and realizes the cold and hot air flow through the automatic air distributor. Automatic control realizes diversified applications and high-degree integration. It has the characteristics of one machine with multiple functions, reducing the overall consumption of compressed air, improving the utilization rate of cooling capacity and heat of small vortex tubes, and improving its energy-saving level.

Problems solved by technology

At present, the application of vortex tube cabinet refrigerators is scattered and the integration level is low. In many applications, one vortex tube refrigerator is installed in one cabinet, which consumes a lot of compressed air, which indirectly results in large power consumption, and even overloads the air compression device, increasing maintenance costs. ; and the current vortex tubes used for refrigeration are all manually controlled, which are easily affected by the fluctuation of compressed air pressure, resulting in unstable air flow temperature. If the air flow temperature is too high or too low, it will affect the work of cabinets, constant temperature chambers, etc.; The hot air flow generated at the hot end of the tube is not fully utilized, resulting in wasted energy
