Structure of Refrigerant Cycle Figure 4 shows the refrigerant piping system diagram of this system. The indoor units do not have a refrigerant control mechanism but only a heat exchanger and a blower. In the multi-controller, the refrigerant flow regulating valve and a dedicated temperature type expansion valve for cooling are connected in series in the liquid side branch circuit. A bypass is installed between the liquid side circuit and the gas side circuit to form a refrigerant superheat detection circuit at the outlet of the evaporator during cooling operation.
This work is now being extended to test the sensitivity exchanger area and its distribution within the system. to total heat CONCLUSIONS The work so far on the compression-absorption cycle shows that it can achieve better performance than the simple fluid cycle and this is particularly so for high output temperatures. Although the COP enhancement is greater at larger source and sink temperature glides the cycle still shows superior performance, when optimised, over conventional systems even for glides as low as 5K.
