Review of Sharp AH-XP18MV 1.5Ton Eco-Inverter Air Conditioner

I have purchased AH-XP13PMT for INR 34500 at Hyderabad. is it a good price? Installation, stabilizer extra. I am not sure if Stabilizer is required for Inverter models.

Its best price. In Mumbai for PMT 1 ton model minimum price i am getting is 35500. (Installation 1500 extra).
 
36000 includes installation, stabilizer, brackets etc.

I would compare this to PMT. Also probably get the 0% finance scheme.

The running amp is 4.8 for this and 7 for PET/PMT etc. as reported by udaykhan.

So I have a feeling that the current models are inferior to maintain the price.

I think you cannot compare 13 LV directly to PMT.
As features of it is similar to PET model like no 4 way swing, no digital display.
(But it is having plasmacluster ion & self cleansing function like PMT)

Power (watts) = Voltage (volts) X Current (amperes)

Both ACs have identical wattage, therefore your hypothesis that low running current translates to better efficiency is just plain wrong.
 
No. What I meant was that it seems that the DC motor of the compressor spins down to using as less as 4.8 amps.

I have long experience of DC motors of all sizes in my industry. Its speed can be varied by varying the supply voltage. So I assume that if the running current is 4.8 amp then the supply voltage has also dropped. This should mean use of less energy. These motors are theoretically infinitely variable. But the current required to overcome the minimum friction is always there.
 
Sharp AH-XP13LV

Indoor Unit [IDU]: Sharp AH-XP13LV
Outdoor Unit [ODU]: Sharp AU-X13LV
Cooling Capacity Range [kW]: (0.8 - 3.67 - 4.20)
Cooling Capacity Range [BTU/Hr]: (2,732 - 12,531 - 14,341)
Cooling Capacity Range [Ton]: (0.23 - 1.04 - 1.20)

Hi Sandeep,

How/where did you get the min-optimum-max numbers from? The Sharp brochure only lists the optimum figure (3.67kW). Is there a way to calculate it or it's released by the manufacturer?

Rgds,
Uday

This is where you are wrong.

To get the same power (!010 watts) with low current means that the voltage goes up, not down.

A 110V AC will use double the current of a 220V AC for the same power.
 
Sir, we are talking a variable speed DC (not AC) motor and a variable compression. The motor of compressor reduces the rpm to reduce compression and thus reduce cooling. This can be seen in the variable BTU rating.

These figures are there on their site and also other sites. I am unable to find similar details for their current models PET PMT PHT etc.

Can someone calculate EER of Carrier 1 ton Superia Plus inverter AC ?
Split AC | Carrier Midea

Some data is missing from there catalogue. I am not able to find out rated cooling capacity & thus not able to conclude on its compressor efficiency.

Thanks.

Taken from Carrier Catalouge
For Model :GWRAC012ER030
Cooling Capacity* Btu/Hr 12600
Cooling Input Power* Watts 1197

Conversion Factor for Cooling Capacity of 1 Btu/Hour = 0.29307107 watts
So Cooling Capacity of this Airconditioner is = 12600X0.29307107=3692.7 W

EER= Cooling Cap in W/ Input Power in W= 3692.7/1197=3.084

Hope above is clear - the same can be done for other models also.

Note that the above figs are for the designed Capacity. In case of an inverter model the power drawn by the compressor varies depending on the load - goes higher at start condition and reduces when the room cools. The cooling capacity also varies accordingly though not in an exact linear fashion. It will be a safe assumption that the EER will be lower at other loads for the same Air conditioner.

I am not an expert however in brief the Invertor Air Conditioner has a variable speed A.C Motor ( Not a DC motor) which draws power based on the cooling load.
See below wiki link for a very brief explanation.

It means Carrier AC have not got good EER and they are hiding the same. It is not possible for a common person to calculate EER.:indifferent14:

I hope the indian government makes mandatory for even inverter AC to calculate EER on some common industry formula like Singapore EER. It would help the people know whether there inverter AC is made up of 5 Star or 3 Star compressor!:cool:
 
I have one doubt-
In normal ac if we go for 1.5 ton instead of 1 ton ac then the compressor more often is on standy mode whereby moisture level increase.

In case of inverter ac is the same case ???

I am asking this question because say i have 130 square feet room. Say sharp 1.1 ton ac cost 38,000 then 1.5 ton should cost 52,000. (38*1.5/1.1). But strangely enough same model 1.5 ton cost only around 43,000.
So if there is no financially constraint 1.5 ton is better, isn't it ??
I have listed the pros, what are the cons ???
 
An inverter AC never suts down fullu, instead it slows down so I guess the moisture problem will be less compared to a conventional AC.

Again if you go for a higher capacity Inverter model the AC will be operating at a low capacity most of the time and probably this will be at a lower efficiency (Lower EER). If you can look at the power consumption figs for 1 ton full load and 66% load for 1.5 Ton you will get an idea.

BTW: for a 130 Sq Ft room a 1.5 tonne is really not high capacity. You will need higher capacity if any of the walls/windows is exposed to western sun. Also if you have a open roof top.
