To Ramaswamy,


Experts, please help.

I wanted to buy Air-con System 3 and visited couple of shops and confused.

I want to install in 3 rooms. Most likely I turn on only two air-cons as third room is a guest room.

Typical usage is as follows.

Master room (3.3 x 4.2 meter), On between 11.30 pm to 6 am
Bedroom 2(3.3 x 4.2 meter), On between 8 pm to 5.30 am
Bedroom 3(4.0 x 4.2 meter). Seldom on. May be monthly once.
All 3 rooms, 9k btu will be sufficient.

1) What is full load? Full load is when the compressor is running @ 100% capacity. (When on all 3 units)
2) What is part load? Part load is when the compressor is running @ 50% capacity. (When on 1-2 units)
3) I want to buy ME Starmex but Sales man suggested MHI. He says MHI is new and low power consumption compare to ME which is 8 year old technology. I looked at energy star and but confused

Full Load:2.18
Part Load:0.72
Cooling capacity 7.31 Kw

Full Load:1.48
Part Load:0.58
Cooling Capacity:6.19 Kw

Since the cooling capacity for Both Aircon is different, How to determine? If Cooling Capacity of MHI is increased to 7.31 kw then what will be the Full Load and Part Load of MHI Air-Con? Can some one help me to understand?

ME full load is higher as their KW output is higher, MHI has a lower KW output thus load rating is lower.
Each bedroom fcu is 2.5KW, 3 is 7.5KW, Thus ME compressor is balanced, but for MHI, the compressor KW is only 6.19KW, the total btu output is smaller then ME.
But does not affect u, as u seldom on all 3 units @ the same time.

4) MHI - Is Auto cleaning but ME is manual cleaning which we can open and clean. How critical is this feature? What you recommend?
Not important. (IMO)

5) Anyone have experience with Midea? Is it reliable? How about cooling ?
Not recommended (IMO)

Thank you in advance for your help.
