3. Installation
3.1.2 Heater /cooling distribution system
Note:
Buffer tank is always recommended to be included in the system , especially when the distribution system has
water volume less then 20L/W. It should be installed between heat pump and distribution system , in order to:
1) Ensure heat pump unit has stable and enough water flow rate.
2) Store heat to minimize fluctuation of system heating/cooling load.
3) Extend the water volume of distribution system for proper working of heat pump unit.
If distribution system has enough water volume and can ensure the water flow rate of heat pump system , buffer
tank can be excluded in the system . But in this way , please move temperature sensor Tc (Cooling/heating
temperature sensor ) to water return pipe to minimize the fluctuation of water temperature caused by compressor
speed changes.
