01. 
Yuchun Heat Pump is of individually closed circuit and monolithic structure and it has capabilities for cooling, heating, cooling by outdoor air, and ventilating. And it can be installed indoors or outdoors without restriction. 

 02. 
Yuchun Heat Pump performs high efficient continuous heating operation. It further resolves ice formation on evaporator of air cooled heat pump by adopting Hot Gas & Hot Defrosting adaptable for cold areas and it also gains around 30 % of heating capacity. 

 03. 
Yuchun Heat Pump ventilates indoor space without loss of energy residue in exhaust air, which results in reducing operating power and energy. 

 04. 
Yuchun Heat Pump recovers latent heat contained in water condensed on surface of evaporator, which also saves operating power. 

 05. 
Yuchun Heat Pump can occasionally adopts outdoor-air-cooling methodology. i.e., by taking outdoor fresh air 100 % into indoor space during season change when outdoor temperature appears to be a bit lower than that of indoor space. During this mode of operation, as compressors stop and only fans operate, operating energy greatly decreases. 

 06. 
Yuchun Heat Pump is controlled for temperature, humidity, ventilating air flow rate by built-in MICOM and also remote and central controlled. 

 07. 
The constant temperature humidity control is done by reheat circuit built in the same cycle. Yuchun Heat Pump can optionally be equipped with constant temperature humidity control that has no additional reheater like electric heater or hot water coil or steam coil. If compared with conventional contant temperature humidity control, it requires considerably less cost for equipment and operation. 

 08. 
Electric power demand control can be done to level peak of electric power by using sequential control of individual group or zone of Heat Pump. 

 09. 
Environment-friendly
 Yuchun Heat Pump does not emit any pollutants because it does not use fossil fuels or water. 

 10. 
Simplicity in structure of machine and system
 Yuchun Heat Pump does not need cooling tower, cooling water pump, cooling water piping, cool and hot water piping, tankage, etc. 

 11. 
Yuchun Heat Pump needs no water. It consequently does not bring the system to problems like breakdown due to freeze, leakage, corrosion, etc. or spread of germ or city water bill. 

 12. 
Simplicity in operation and maintenance, and long life
 While conventional HVAC&R consists of various components such as boiler, compressor, pump, piping, cooling tower, etc., Yuchun Heat Pump is just a single unit. That means not only easy operation and maintenance but less probability of problem and long life of machine. 
 
 13. 
High Coefficient of Performance, COP
 Several official technical papers issued by Korea Institute of Science and Technology, KIST show that Yuchun Heat Pump has technical characteristic of lower input power against output heat than conventional ones.
