Intelligent double-vortex-tube refrigerating and heating system

Abstract

The invention discloses an intelligent double-vortex-tube refrigerating and heating system. The intelligent double-vortex-tube refrigerating and heating system is mainly composed of a flow regulating valve, a main vortex tube, an auxiliary vortex tube, an air inlet valve, a main refrigerating coefficient control valve, an auxiliary refrigerating coefficient control valve, a hot air current temperature sensor, a cold air current temperature sensor and a controller, and the controller is used for regulating and controlling the main refrigerating coefficient control valve and the auxiliary refrigerating coefficient control valve according to temperature information; the controller is used for opening or closing the air inlet valve according to flow opening data, so that the auxiliary vortex tube stars or stops working. By means of the characteristics that the vortex tubes integrate refrigerating and heating and the refrigerating capacity is identical to the heating capacity, accurate control over refrigerating air current temperature and heating air current temperature of the vortex tubes is achieved through a control system, automatic control over cold air currents and hot air currents is achieved through an automatic air current distributor, diversified application and high-degree integration are achieved, and the intelligent double-vortex-tube refrigerating and heating system has the advantages that multiple purposes are achieved, the total use amount of compressed air is reduced, the utilization rate of the refrigerating capacity and the heating capacity of the small vortex tubes is increased, and the energy saving level is improved.

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
