Cooling:
in cooling mode, the refrigerant is condensed in the outdoor unit and evaporated in the indoor unit. Via
the heat exchange with water in the indoor unit, the temperature of water decreases and it releases heat while the
refrigerant absorbs heat and evaporates. With the help of wired controller, the outflow temperature can meet the
user’s requirement. Through the control of valve, the low-temperature water in the system is connected with indoor
fan coil and underground pipe, and exchanges heat with the indoor air so that the indoor temperature decreases to
the required range.
Heating:
in heating mode, the refrigerant evaporates in the outdoor unit and is condensed in the indoor unit.
Via the heat exchange with water in the indoor unit, the water absorbs heat and its temperature increases while the
refrigerant releases heat and is condensed. With the help of wired controller, the outflow temperature can meet the
user’s requirement. Through the control of valve, the high-temperature water in the system is connected with indoor
fan coil and underground pipe, and exchanges heat with the indoor air so that the indoor temperature increases to
the required range.
Water heating
: in water heating mode: the refrigerant evaporates in the outdoor unit and is condensed in
the indoor unit. Via the heat exchange with water in the indoor unit, the water absorbs heat and its temperature
increase while the refrigerant releases heat and is condensed. With the help of wired controller, the outflow
temperature can meet the user’s requirement. Through the control of valve, the high-temperature water in the
system is connected with the coil pipe of bearing water tank, and exchanges heat with the water in the water tank
so that the temperature of water tank increases to the required range.
C water heating
: when cooling mode exists together with the water heating mode, the user can set the
priority of these two modes based on the needs. The default priority is heat pump. That is under the default setting,
if cooling mode exists together with the water heating mode, the heat pump gives priority to cooling. In that case,
water heating can only realized with e-heater of the water tank. Inversely, the heat pump gives priority to water
heating and switches to cooling after finishing water heating.
