Spray tank type heat exchanger and using method thereof

Abstract

The invention relates to the technical field of heat exchangers, in particular to a spray tank type heat exchanger and a using method thereof. The spray tank type heat exchanger comprises an outer barrel-shaped shell and a shaft core arranged inside the shell. A spiral coil pipe winding on the shaft core is arranged between the shell and the shaft core. A cooling medium flows in the spiral coil pipe. The cooling medium enters through a coil pipe inlet formed in the lower portion of the shell and flows out through a coil pipe outlet formed in the upper portion of the shell. A refrigerant flows through the space between the interior of the shell and the exterior of the spiral coil pipe, and the refrigerant enters and flows out through a condenser inlet / outlet structure or enters and flows out through an evaporator inlet / outlet structure. The spray tank type heat exchanger can be applied as a condenser as well as an evaporator, an independent evaporator is omitted, thus, a connection circuit structure is simpler, the heat exchange cost is reduced, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a spray tank heat exchanger and a method for using the same. Background technique [0002] As the country implements environmental protection and energy saving policies to realize a conservation-oriented society, high-efficiency and energy-saving water source / ground source heat pump units have been developed rapidly. Heat pump units need to switch between cooling and heating modes. The system pipeline includes compressors, condensers, Throttling components, evaporators and other components. Heat pump units usually use spray tank heat exchangers as condensers. Due to structural limitations, existing spray tank heat exchangers can only be used as condensers to exchange heat from gaseous refrigerants into liquid refrigerants. , and cannot be used as an evaporator. If you want to cool the cooling medium, you need to connect the evaporator and other corresponding auxiliary eq...

Problems solved by technology

Heat pump units usually use spray tank heat exchangers as condensers. Due to structural limitations, existing spray tank heat exchangers can only be used as condensers to exchange heat from gaseous refrigerants into liquid refrigerants. , and cannot be used as an evaporator. If you want to cool the cooling medium, you need to connect the evaporator and other corresponding auxiliary equipment. This structure makes the heat exchange cost of the heat pump unit high, the connection structure is complicated, it is not easy to operate, and the heat exchange efficiency not ideal
