Indoor coil

Abstract

An indoor coil including at least one coil slab. The at least one coil slab including a pair of coil slab end surfaces extending between a pair coil slab faces, a coil slab axis, and a plurality of conduits, operably coupled to one another, disposed therein. One of the pair of coil slab end surfaces forms an angle greater than or equal to 45 degrees and less than 90 degrees with the coil slab axis, and the plurality of conduits are arranged in a staggered configuration.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application is related to, and claims the priority benefit of, U.S. Provisional Patent Application Ser. No. 61 / 910,716 filed Dec. 2, 2013, the contents of which are hereby incorporated in their entirety into the present disclosure.TECHNICAL FIELD OF THE DISCLOSED EMBODIMENTS[0002]The presently disclosed embodiments generally relate to heating, ventilation, and air-conditioning (HVAC) systems, and more particularly, to an indoor coil.BACKGROUND OF THE DISCLOSED EMBODIMENTS[0003]In a conventional refrigerant cycle, a compressor compresses a refrigerant and delivers the compressed refrigerant to a downstream condenser coil. From the condenser coil, the refrigerant passes through an expansion device, and subsequently, to an evaporator coil. The refrigerant from the evaporator coil is returned to the compressor. In a split system heating and / or cooling system, the condenser coil may be known as an outdoor heat exchanger and the eva...

AI Technical Summary

Benefits of technology

The patent describes an indoor coil for use in a fan coil assembly or an HVAC system. The technical effects include efficient cooling or heating for indoor spaces, with a coil structure that allows for the proper flow of liquid and includes a plurality of conduits arranged in a staggered configuration. The coil slabs may be arranged in a "V" configuration or at angles greater than or equal to 45 degrees and less than 90 degrees with the coil slab axis. The fan coil assembly also includes a fan and an auxiliary heating assembly, and the HVAC system includes a heat pump and fan coil assembly. Overall, the patent provides technical solutions for improving the performance and efficiency of cooling and heating systems for indoor spaces.

Problems solved by technology

However the ends of conventional rectangular shaped evaporator coils provide inefficient sources of heat transfer and can cause higher internal pressure drops as the airflow across the ends are minimal.
