Conduit for using only at one end of, and for mildly defrosting, an evaporator without causing excessive heat to affect the evaporator or occupants in proximity to the evaporator

Abstract

A conduit used only at one end of, and mildly defrosting, an evaporator without causing excessive heat to affect the evaporator in proximity to the evaporator. A tube includes at least one central passageway, at least one peripheral passageway, and at least one intermediate passageway. A refrigerant flows through the at least one peripheral passageway. A hot refrigerant gas flows through the at least one central passageway, and blends with the refrigerant flowing through the tube so as to form a defrosting blend. The defrosting blend defrosts along the full length of the tube, which occurs very rapidly due to contact of the hot refrigerant gas on the way to the end of the tube and then back through the at least one intermediate passageway of the tube as the blend.

Description

BACKGROUND OF THE INVENTION[0001]A. Field of the Invention[0002]The embodiments of the present invention relate to an evaporator conduit, and more particularly, the embodiments of the present invention relate to a conduit for using only at one end of, and for mildly defrosting, an evaporator without causing excessive heat to affect the evaporator or occupants in proximity to the evaporator.[0003]B. Description of the Prior Art[0004]Evaporators, cooling coils, and heat exchangers are used in various applications in the HVAC / R industry for the purpose of cooling, chilling, or freezing. In doing so, temperatures surrounding these devices tend to freeze moisture being removed by the evaporators, thereby reducing their efficiency, and thereby increasing the cost of operation and negatively affecting the quality of the product or the comfort of the occupants in the case of comfort cooling applications.[0005]To solve the problem, the evaporators have to be defrosted so as to operate as eff...

AI Technical Summary

Benefits of technology

The present invention provides a conduit that allows for the use of one end of an evaporator for mild self-defrosting without causing excessive heat that affects the evaporator or occupants nearby. The conduit includes a tube with at least one intermediate passageway between the central and peripheral passageways. A refrigerant flows through the peripheral passageway, and a hot refrigerant gas flows through the central passageway to form a defrosting blend that causes a mild defrost along the full length of the tube without applying excessive temperatures or pressures to the evaporator. This technology avoids the disadvantages of prior art.

Problems solved by technology

In doing so, temperatures surrounding these devices tend to freeze moisture being removed by the evaporators, thereby reducing their efficiency, and thereby increasing the cost of operation and negatively affecting the quality of the product or the comfort of the occupants in the case of comfort cooling applications.

In the past, there have been disadvantages and high operational costs due to the use of these methods.

Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, nevertheless, they would not be suitable for the purposes of the embodiments of the present invention as heretofore described, namely, a conduit for using only at one end of and for mildly sell-defrosting, an evaporator without causing excessive heat to affect the evaporator or occupants in proximity to the evaporator.
