2. Various functions are operated under different environmental conditions, and the throttling device is shared, so that the pressure and the supercooling degree of the refrigerant are difficult to stably adjust.
3. One set of system designs each function, needs the mode that the efficiency was chosen or not to realize several kinds of operational modes, so the general physical stamina is poor in effect.
4. The refrigerant is in low pressure state at the inlet of the valve, and the internal leakage is too large when the outlet is in high pressure state, so that the compressor does no work, and the energy loss is large.
5. In one set of system, when certain functions are operated, the refrigerant is repeatedly throttled by the system, and great energy loss is also caused.
6. The hot water heat exchanger in the system is connected with another heat exchanger in series, so that the heat loss is large and the hot water making speed is low when the hot water is made.
