Description | The U.S. Coast Guard is conducting market research to determine domestic availability of Ductless-Split Heating and Air Conditioning (A/C) Systems. Specifically, Ductless-Split Heating and A/C Systems that are manufactured in the United States in sufficient and reasonably available commercial quantities of satisfactory quality. The applicable North American Industry Classification System (NAICS) code is 238220 Plumbing, Heating, and Air-Conditioning Contractors. Ductless-Split Heating and A/C Systems are subdivided into three categories: Mini-Split, Multi-Split, and VRF/VRV. Mini-Split A/C and Heat-Pumps The lowest cost and most common system has one outside unit and one indoor unit. This type of system is generally used for single-zone cooling and/or heating and is common in residential and small commercial settings. Multi-Split A/C and Heat-Pumps This system adds complexity by allowing a single outside condensing unit to supply refrigerant to multiple indoor units for independent temperature controlled zones. The refrigerant flow is constant and the entire system must be in the same mode (heating/cooling). This means that certain zones cannot be cooling while others are heating. This type of system is generally used to condition a suite of offices or a small group of rooms. VRF/VRV This system works like the multi-split units, but provides the added benefit of being able to heat some zones while cooling others. The refrigerant compressor is capable of adjusting the flow based on the heating and cooling demands, which makes the system more efficient. Additional devices and controls inherent to VRF/VRV systems also contribute to higher efficiency, but also increases cost and complexity. In order for the Ductless-Split Heating and A/C Systems to be considered manufactured in the United States, all manufacturing process must take place in the United States and the cost of components mined, produced, or manufactured in the United States must exceed 50 percent of the cost of all the components. Components of foreign origin of the same class or kind for which nonavailability determinations have been made are treated as domestic. |
