Abstract

A modular heating and cooling unit comprising an independent set of headers for each of the heating and cooling loads and the source. A bank of these modular units provides a system that is capable of incremental simultaneous heating and cooling and redundancy. Valves in the internal piping of the unit eliminate the need for valves in the headers between units. This substantially reduces the overall footprint of the unit. Because of the parallel flow between the heat exchangers and the heating and cooling load, the modules can be operated in cooling mode and heating mode in any order.

Abstract

A modular chiller unit comprising flooded shell-and-tube liquid heat exchangers that are interconnectable with like units to provide a bank of chillers with one large flooded evaporator and one large flooded condenser. The refrigerant circuits are interconnected so that the compressor in one operating unit circulates refrigerant in parallel through the heat exchangers of other non-operating units in the bank. Connecting flanges on the ends of the evaporator and condenser shells facilitate connection between units and also allow stable stacking of the heat exchangers in a single unit. A bank of these modular chillers may further include end caps for the heat exchangers in the last unit and water connecting heads for the heat exchangers in the first unit. This chiller bank combines the convenience and versatility of modular chiller units with the operating efficiency of large flooded evaporator and condensers.
