Remaining air in the water circuit will be automatically removed
via the automatic bleed valve.
Four temperature sensors determine the water and refrigerant
temperature at various points.
5.1-T2B; 5.2-T2; 5.3-Tw_out; 5.4-Tw_in; 5.5-T1
The manometer allows readout of the water pressure in the water
circuit.
If water flow is below 0.6 m
water flow reach 0.66 m
The pump circulates the water in the water circuit.
Heat exchanging between water and refrigerant.
The pressure relief valve prevents excessive water pressure in the
water circuit by opening at 43.5psi(g)/0.3MPa(g) and discharging
some water.
They are for preventing frozen.(14.2 is optional)
The backup heater consists of an electrical heating element that will
provide additional heating capacity to the water circuit if the heating
capacity of the unit is insufficient due to low outdoor temperatures, it
also protects the external water piping from freezing during cold periods.
