HVAC question: can one condenser support two air handling ...To my knowledge, there are no condensing units that have "two connections" for separate air handling units. Mitsubishi, LG, Sanyo, Fujitsu and others manufacture what are called ductless mini-split air conditioners and heat pumps. One outside unit can handle from one to four "heads" or indoor units. They come in a variety of BTU capacities.

Many Evaporators, One Condenser, No Ducts - ACHR News"Customers were saying they liked the ductless products, but they had no place to put multiple condensing units," he says. "They were asking for multiple indoor units but only one condensing unit that they could stick up on the roof or some other obscure location. We provide that capability with the Eco Multi." For now, the system is ...

Two evaporator coils, one condenser - InspectionNewsRe: Two evaporator coils, one condenser It is not at all uncommon to have multiple evaporators on a single condensing unit. If it is sized incorrectly the problem could be frozen coils or lack of sufficient cooling.

Installation and Operation Manual Table of ContentsThe field wiring to the condensing unit may be connected from any iRC board on the system. All 24 volt wiring must be run separate from the line voltage wiring. • Low voltage wiring to the condensing unit must be 18 gauge minimum. For low voltage wiring, maximum distances are: Condensing unit to iRC board 500 ft.

INSTALLATION, OPERATION AND MAINTENANCE MANUALroom around the unit for regular inspection and service. For multiple unit sites, do not locate units where the air discharge from one condensing unit will enter into the air intake of other units. Roof mounted condensing units should be located above supporting walls, over storage areas or spaces not sensitive to noise or vibration.

Multiple Evaporator System: - Ref wikiIf the evaporator temperature is the same, the system uses only the low side of the float, or TEV to control the refrigerant. If two or more evaporating temperatures are desired (frozen food temperature and the temperature of the cooling water, for example), the device must be used to keep one of evaporators for a lower external pressure.

HVAC Multi-Split Variable Refrigerant Flow (VRF) SystemsHVAC Multi-Split Variable Refrigerant Flow (VRF) Systems A. Bhatia, B.E. VRF (Variable refrigerant flow) is an air-condition system configuration where there is one outdoor condensing unit and multiple indoor units. The term variable refrigerant flow (VRF) refers to the ability of the system to control the amount of refrigerant flowing to the

PRESENT THEORY AND PRACTICE Kumbhar A. D. [1] developed the system with a single compressor and three evaporators of 1 tone, 0.6 tons, 0.4 tons capacities. He used reciprocating hermetic compressor

Operating Characteristics of Multiple Evaporators and ...Schematic of a MLHP. (a) Heat loads to both evaporators; (b) Heat load to one evaporator. evaporators (forward flow). The vapor generated in Evap. 1 is flows to the condensers through the vapor line. On the other hand, a part of the vapor flows into Evap. 2 through the vapor line, and the condensed in Evap. 2.

Multi-Evaporator System - WikipediaThere may be arrangements possible for multi evaporators on the basis of single or multi compressors. If refrigerant from each evaporator compressed in the same single compressor then it is called as Multi-evaporator single-compressor system. Single compressor-individual expansion valve

CONDENSING UNIT INSTALLATION INSTRUCTIONSThe condensing unit must be installed on a solid, level mounting pad that will not settle or shift. Isolate the pad from the building structure to avoid possible transmission of sound or vibration from the condensing unit into the conditioned space. The condensing unit foundation should be raised to a minimum of 3" (7.6 cm) above finish grade.

REFRIGERANT PIPING INTRODUCTION - RSES.orgWhen designing a system, the engineer needs to maintain a solid column of liquid refrigerant to the flow control device, such as a thermostatic expansion valve, low-side float valve or high-side float valve, and make sure that column will stay at a reasonable working temperature.

Evaporator - WikipediaThe energy consumption for single-effect evaporators is very high and is most of the cost for an evaporation system. Putting together evaporators saves heat and thus requires less energy. Adding one evaporator to the original decreases energy consumption to 50%. Adding another effect reduces it to 33% and so on.

Two Condensers in the same unit [Archive] - Refrigeration ...two condensers in the same unit, it is possible.But what for? You could have many reasons. If your system need to condense more because it don't reject a maximum of warm from gas,or your air condenser location is not enough cool. In all case you can connect two condensers but be sure about the reason.
