LHP as the best energy efficient solution to contain global warming

[CJamesTay]

Japan Authority has recognized in their Institute of Social & Economic Affairs that heat pump technology is the best energy efficiency product to contain global climate change, high energy costs and pollution

As compared to other energy technologies like solar PV, wind, biomass, waste recycling, bio-fuel and others, heat pump does not need infrastructure and grids to connect

Heat pump functions basically by using atmospheris air, converting heat to cool and cool to warm air depending on the climate and situation. Latent heat pump is relative a new study and it is being conducted by the New Energy Development Agency, Japan to serve the purpose

Can a nation like Thailand be interested to conduct R&D and invest in this type of high efficient technology like Latent Heat Pump?

Do you think that the thai university has experts in this field?

I would like to invite fellow thais who are interested to contact me at cjamestay1@gmail.com

what exactly is a latent heat pump? What do you have to support the claims. I personally believe energy efficiency achieved by great building design and passive methods including appropriate use of and often rejection of solar heat and light.. Could you send me to more information?
IM VERY INTERESTED. Randy

Excuse me but there is no such thing as a free lunch.

I don't think you know what a heat pump is and I don't even know why you are comparing it to power sources or recycling.

A traditional Heat Pump is a reversible air conditioner. In the summer the condenser coil (outside) dissipates heat that is absorbed by the evaporator coil (inside) and in the winter the refrigerant flow is reversed -cold outside, hot inside.
It is quite efficient when used in heating mode in area that doesn't get too cold (40F/5c or above) but not any more efficient in cooling mode than a conventional AC.
Regardless, it still uses electricity to compress the refrigerant and that has got to come from somewhere.

The LHP, Latent (heat storage) Heat Pump, relies on an external thermal mass to absorb the heat (cooling cycle) or gives out heat (heating cycle), a separate coolant loop transfer the heat from the inside heat exchanger unit and dumps it in the thermal mass or pick up heat from the thermal mass and dumps it inside.

In practice, there is no need for heating cycle in anywhere but Northern Thailand and only a few days out of the year so it's going to be all about cooling.

The LHP cooling mode use large body of salt water or ice as thermal mass.
The thermal mass is cooled by standard refrigeration unit during night time or off-hours when electricity is cheaper for commercial users and hence the possible financial savings.
Overall, the system doesn't use appreciably less electricity unless installed in an area that gets significantly colder at night (50F/10C or lower) and impractical for a small scale deployment.

Like, where are you going to put that thermal storage unit in your 70 square meter apartment ?

Yes, there are ppl in Thailand who actually know what it technology is about.
Contact you ? Why ?
I mean, obviously you have no expertise to offer and your notion is a FAIL.
Are you looking for a free lunch ?
