Globally, ductless heat pumps are the standard method of heating and cooling residential and commercial buildings. In North America the post-war building boom favoured ducted systems but we since realized there are advantages to ductless systems, especially to cool.

For commercial applications, Variable Refrigerant Volume (or Flow) systems are quickly becoming an option of choice in North America. In Japan where VRV/F was invented in 1982 half of all small commercial buildings use this ductless system.

Abstract: The application of the variable refrigerant

volume multi-zone air conditioning systems has met

with mixed results since the publication of the Design

Standard for Energy Efficiency of Public Buildings.

This paper analyzes the characteristics of the variable

refrigerant volume multi-zone air conditioning system,

and discusses the advantages of its application.

Key words: Design standard for energy efficiency of

public buildings, variable refrigerant volume air

conditioning system, energy efficiency of buildings,

application
