R410A TOTAL HEAT RECOVERY MODULAR UNIT


Withair's total heat recovery modular air-cooled chiller & heat pump unit uses the environment-friendly refrigerant R410A and combines the features of Withair's air-cooled chiller & heat pump unit and air-source heat pump water heater unit. It has five modes: A/C cooling, A/C heating, heat recovery, heat pump water heating, A/C heating + heat pump water heating, widely applied in places requiring central air conditioning and water heating, such as: hotels, schools, restaurants, hospitals, villas, bath centers and industry use.


—— Free Domestic Hot Water ——

In the A/C cooling mode, the unit can recover waste heat and provide free domestic hot water to 55℃. The unit replaces the boiler to meet the user needs for hot water, saves initial investment, eliminates the need for machine room, and saves the building area and energy for environmental protection.


—— Less Occupied Area ——

A single module covers a floor area of only 1.86m2 which is the smallest in the industry, leaving larger valuable space for customers. The unit can substitute the boiler, eliminates the need for machine room, and saves initial investment and building area.


—— Compact Design And Complete Functions ——

In the A/C cooling mode, the unit can recover waste heat and provide free domestic hot water to 55℃. The unit replaces the boiler to meet the user needs for hot water, saves initial investment, eliminates the need for machine room, and saves the building area and energy for environmental protection.


—— Efficient Components Providing Higher Efficiency —— 

The unit employs efficient shell and tube heat exchanger, fan, and heat recovery unit, with optimized pipeline design, providing comprehensive energy efficiency up to 8.24 under conditions of cooling + heat recovery.


TOTAL HEAT RECOVERY OPERATION MODE


There are five operation modes including cooling, heat recovery, A/C heating, heat pump water heating, heating + heat pump water heating, which satisfy the user needs for air conditioning throughout the year and provide domestic hot water.



—— Cooling Mode ——

In summer or transition season needing cooling but not hot water, this mode can be used. In such case, the unit operates for cooling only, just like a standard air-cooled heat pump unit.


—— Heating Mode ——

In circumstances where only domestic hot water is needed instead of cooling or heating, this mode can be used. In such case, the unit only provides domestic hot water, just a standard air source heat pump water heater unit.


—— Heat Recovery Mode ——

In circumstances where both cooling and production of domestic hot water are needed, this mode can be used. In such case, the unit automatically selects the optimal operation mode based on the needs for air conditioning and water heating to produce chilled water for air conditioning and domestic hot water for everyday use.


—— Heat Pump Water Heating Mode ——

In circumstances where only domestic hot water is needed instead of cooling or heating, this mode can be used. In such case, the unit only provides domestic hot water, just like a standard air source heat pump water heater unit.


—— Heating + Heat Pump Water Heating Mode ——

In winter or other circumstances where both heating and domestic hot water are needed, this mode can be used. In such case, the water heating mode is preferred by default to ensure use of domestic hot water; then at the “idle time” when the demand for hot water is satisfied, the unit automatically switches to the heating mode to meet the needs for heating. Users may set the heating mode as the priority as required to ensure heating effect.
