New Heat Pump Forum

[Argus]

.

Here is a new sub section on HEAT PUMPS in the Air Conditioning forum.

Typically, most reverse cycle heat pumps are small air conditioning systems for human comfort, but there?s more to it than that.

We are aiming to provide a platform for discussion, questions and answers, and even promotion of the general technology of heat pumps.

For example, non-comfort applications now include ground source heating, industrial process dehumidification, swimming pools, heat reclaim technologies and lots more, all involving heat pumps as their core technology. Many of these applications are taking up the use of alternative refrigerants, especially Ground Source systems.

We aim to air discussions on the applications, merits and problems you encounter with heat pumps and to hopefully attract more members to post here who are active in this area.

It's a good idea to focus on heat pump in this place!
Suggest wrap up related posts in RE forum into this sub section and set up a good start.

best regards

Glad to see that you are starting a new sub section on heat pumps as I am in the process of introducing such equipment for domestic heating and will hope to find lots of technical assistance on this forum.
I wish to send best regards to all contributors to this very helpful and enjoyable forum.

This sub-forum is not easy to find which affect interested guys access it. Suggest Boss highlight it in the home page.
Hi Argus/Iceman
Could you please offer a sample project(no matter what application field) and discuss it from the start as a real case procedure? i think all the interested guys can get /share something

I am in the process of installing a water to water heat pump to provide heating for my domestic requirements.
The refrigerant is 407C and I am hoping to produce 60 C on the water cooling the condenser, what is the highest temperature of water can be used on the evaporator within reason ? Nage

Maybe it is hard to use 407c to produce 60 domestic hot water. Or , short time, it do. long time , the compressor will be damaged or influence the using time of compressor.
as to the highest temperature of water can be used on the evaporator, as long as the compressor will not overload, it will be ok.

Higher discharge temp. can be had using R134A. This refrigerant is used in the Calorex ground and Air source units where 65C is acheivable.

generally, the R417A IS OKAY

Hi, I am currently working on my dissertation on the popularity and effectiveness of heat pumps in the UK's market. If anybody has had a heat pump installed (either air or ground source) i would be extremely grateful if i could ask a few questions about your system and your view on heat pumps? thanks very much

Maybe this forum should start with a definition of "heat pump".

Seems it is not just a reverse cycle A/C, anymore.

Maybe this forum should start with a definition of "heat pump".

I'm not certain what the official definition is, but I would define a heat pump as a refrigeration system whose function is heating as opposed to (or as well as) cooling.

As such, this should not be a sub-title under "Air Conditioning" but should have its own title "Heat Pumps", with subtitles of "Heat Pump A/C" and "Heat Pump Water Heaters".

Does this seem reasonable?

This post was going back to 2006 though?

[billliu210]

Yes , i think Gary's opinion is proper.
