Which of the following statements regarding an undercharged TXV system is false?

In an undercharged thermal expansion valve (TXV) system, the refrigerant level is insufficient to adequately fill the evaporator. This situation leads to several specific outcomes in the system's performance.

The assertion that more heat than normal will be transferred to the high side is misleading. In fact, with less refrigerant available due to undercharging, the system has a limited ability to absorb heat from the evaporator. This reduced absorption results in less heat being carried to the compressor and subsequently to the high side of the system. Thus, less heat is effectively transferred to the high side, making the claim false.

On the other hand, the other statements reflect the realities of how an undercharged system operates. It will cool less effectively because there is insufficient refrigerant in the evaporator to absorb the required amount of heat for proper cooling. This also leads to lower pressure in the evaporator, as there is less refrigerant vaporizing to maintain the necessary pressure conditions. Furthermore, the flow of refrigerant will indeed be reduced because the TXV is designed to regulate flow based on the superheat level; without enough refrigerant, there won't be enough vapor to prompt the valve to open to its full capacity.

Therefore, the falsehood of the statement regarding
