The principle and applications of bridge type loops-water source heat pump with 4 functions

Abstract

Bridge type loops-water source heat pump with 4 functions that has bridge type connecting multi-loops, is made up of condenser, evaporator, fan coil unit, hot water tank, indirect heat exchanger and so on 5 hot equipments, by using the connection way of the bridge circuit and 5 pairs of control nodes and 4 T-valves to connect user terminals and water source; in order to control the change of water circulation in multi-loops, and to realize heating, air conditioning, hot water, air conditioning + hot water 4 functions. © 2011 Springer-Verlag Berlin Heidelberg.
