Description

FLUID MIXING AND CONDE NSATION FACILITATORS FOR HEATING AND COOLING SYSTEMS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid mixing and condensation promoting apparatus for a cooling and heating system. In particular, it is provided at an outlet side of an condenser and an inlet side of an expansion valve to mix refrigerant oil and a fluid that is insoluble refrigerant, and promote condensation. To improve efficiency.

The refrigeration cycle applied to the general refrigeration air conditioning system is a refrigerant structure circulates through the pipe in a closed structure of the four strokes of the evaporator, the compressor, the condenser and the expansion valve.

The refrigerant flows through the pipe as a medium for heat exchange, and heat exchange occurs in the evaporator and the condenser during the four strokes, and the refrigerant oil is stored in a tank provided in the compressor as a lubricant for the compressor.

In the process of compressing the gas into a high-temperature, high-pressure gas refrigerant, the refrigerant and the refrigerant oil are in a mixed state and the refrigerant oil is dissolved in the refrigerant.The two fluids are circulated together along the pipe in the refrigeration cycle to return to the compressor. come.

In the refrigeration cycle, when the refrigerant oil compressed together with the refrigerant in the compressor is in a state in which refrigerant which is not easily dissolved is mixed, there is a cause that the efficiency is lowered during the heat exchange process due to the fluidity and the flow decrease in the pipe.

In addition, when the refrigerant and the refrigeration oil flows into the condenser from the compressor, the refrigeration oil is separated and the refrigeration oil shortage occurs due to the phenomenon of staying in the condenser, the evaporator, and various pipe inner surfaces, causing the compressor to overheat.

In order to solve this cause, the addition of various chemical synthetic oils solves even mixing and dissolution of the refrigerant and the freezer oil, but there is a problem in that satisfactory results are not obtained by adding the chemical synthetic oils.

Meanwhile, the air conditioner condensation accelerator of Korean Patent Publication No. 10-1450648 (2014.10.07) has been proposed, and the proposed condensation accelerator is installed near the condenser so that the refrigerant in the mixed state of the liquid phase and the gaseous phase hits the wall. It is configured to be discharged through the so as to promote the condensation of the refrigerant, but there is a problem that the effect is only effective in cooling but not in heating.

In addition, a bubble removing device of Korean Patent Application Laid-open No. 10-2014-116159 (October 01, 2014) has been proposed, and the proposed bubble removing device is intended to remove bubbles, but the mixture of the refrigerant and the dissolution of the refrigerant and the refrigeration oil are promoted. Although it is effective, the cylindrical container is long to form spiral swirl flow by long coil, and the capacity is large, so a large installation place is required when installing the bubble removing device, and a large amount of refrigerant and freezer oil must be added. There was a problem.

The coil spring 360 is for miniaturizing the refrigeration oil in the freon refrigerant is preferably provided as a compression spring. This causes the fluid to resonate at the resonant frequency of the compression spring, thereby locally generating vertical vibration. The vertical vibration generated at this time is a shear force acting on the fluid.

In addition, since the shear force acts on the fluid by the unevenness of the coil spring 360 itself, it is possible to refine the refrigeration oil mainly by the shear force.

In addition, as the coil spring 360 has various shapes of apertures due to the cone shape, the coil spring 360 has various resonance frequencies, and thus vertical vibration causes shear force in the fluid, thereby miniaturizing the refrigeration oil. Even if the size and concentration of the mass changes, the Freon refrigerant can be efficiently polymerized.

At this time, it is more preferable that the impeller 420 is provided with four to twelve blades.

This is because the fluid is mixed in the process of causing the fluid to vortex by colliding with the inner wall surface of the reducer-shaped housing body 110 and the cooling / heating fluid outlet 300, the fluid mixing unit 400 of the fluid is moved downward As the impeller 420 rotates to further mix the fluid, a shear force is generated to promote condensation.

When fluid flows from the high pressure pipe at the outlet side of the condenser CON into the cooling / heating fluid inlet 200, the fluid collides with the cyclone vortex and the inner wall of the housing body 110 of the housing 100. The fluid is primarily mixed by the shear force generated by hitting the male threaded portion 351 of the cooling / heating fluid outlet 300, and the fluid mixed in the lower direction of the housing body 110 is formed in the housing lower cover 130. As the impeller 420 is rotated by the force of the fluid in the process of flowing into the fluid mixing unit 400 provided therein, the fluid is mixed in the secondary, and at the same time, the uniformity can be achieved.

The flow of the fluid is made finer and more uniform due to the cyclone vortex, shear force due to friction or collision between the fluid and vortex formation.
