A check valve should be installed on the heat pump side of the buffer tank to prevent reverse thermosiphoning through the heat pump when it is off. The 2-pipe configuration places the load between the buffer and the heat pump. This allows the possibility of passing heat directly from the heat source to the load without that heat having to first pass through the buffer tank. This enables faster recovery from setback conditions. One limitation of the 2-pipe configuration is that a differential pressure valve that creates a forward opening resistance of 1 to 1.5 psi, or a motorized ball valve, needs to be installed in the heat pump piping to prevent a portion of the flow returning from the load from passing through the heat pump when it’s off. It’s also necessary to keep the tees that connect to the load as close as possible to the tank to allow for good hydraulic separation. 57 condenser heating mode compressor TXV evaporator outside insidePDF Image | Heat Pump Systems 2020
