Transform an air-water heat pump air conditioning

re hello, it is not worth going to Belgium for the refrigeration tools, I have them available, with the explanation that it would be necessary to use them. @ +

yes christophe, I had already looked at the small heat pumps for swimming pools, I had found 500 euros for one of 500w conso with a cop of 2 or 3 I do not remember anymore, but I have a problem and it takes a passage of mini 4m3 and that bothers me a little for my 1m3 tampn, fear of too much stirring.

small question to the specialist Captain is there a little trick to do to avoid this.

Well in my opinion it's not a problem! You will just go up more in T ° and will have a COP (a little) lower!

They say 4m3 / h to guarantee swimming pool performance between 25 and 28 ° CT ° swimming pool. I think there is no problem in reducing the flow ...

4m3 / h it already requires a nice pump of 3 or 400W ... it's a bit silly to put 300W mechanical to heat ...

For the rest I do not see too much downside ... except the lifespan compared to "residential" heat pumps ... but given that their price is 10 times higher ...It would not surprise me that the swimming pool CAP is 5 to 10 times more profitable than the residential CAP!

I'm the one in Belgium who invites Maloche

For your explanations, we are waiting there !!

[Capt_Maloche]

A) Is there an external exchanger? I did not know ... I said nothing then!

I know one who will do a little fridge internship in Belgium next spring !! Chiche? Say yes, say yes, steupléééééééé!

RHHOO, no moo, the exchanger is sheathed on the device, 2 flexible PVC sheaths are used to channel the air

For the internship, it's ok with trappist open bar

Yep, as Christophe says, 4m3 / h is a flow which must correspond to a relatively low delta of T °

if your pump is 3000W in heating mode
the reasonable flow would be with an inlet / outlet delta T ° of 5 ° C:

3Kw / (4.18x5) = 0.143 L / s or 0,5 M3 / h

for a swimming pool the flow rates are higher for the water treatment (sand filter) and also "pulsate" the water for the surface treatment or the massaging jets, because often the heating systems are in series on the circuit

[tigrou_838]

therefore, CAPTAIN, you think that with this swimming pool cap, to associate with a circulator of 0,5m3h that should be good to raise the temperature of the tempo from 1000l to more or less 50degrees.

another question, winter below zero, how does it work?

you have to put the cap inside in a room that does not freeze ??

[Capt_Maloche]

It's not bad for 500 €, do you have a manufacturing link?

By cons to make hot water, table rather 40 ° C (preheating in fact)

By low temperature and high temperature your COP will collapse and ruin all the interest of this assembly

There is already Poolex which seems to me more suitable for the ranges, for the rest and the prices, search on Google at the pool specialist with these names: https://www.econologie.com/forums/pompe-a-ch ... t8428.html



It is the period of the promotions currently I believe

[Christophe]

heating systems are standard on the circuit

For swimming pool heat pumps yes, for the rest (exchanger on boiler or solar panels therefore at higher T °) no, it is generally in ByPass (with adjustment valve).

There are swimming pools which even have their dedicated boiler (usually gas) !!

Vi Vi, I did this for an infinity pool in Barbados
The customer is king, you can't always place solar

At the very beginning of the subject, it is clearly stated that it is not necessary to have refrigeration equipment ...
But this means that the welds produced are perfectly sealed as well as the entire circuit ...
I have already installed (not at home) several air conditioners from B --- O D ---- T first price and they are preloaded at the factory. Once installed and connected, they indicate a fairly simple procedure for evacuating / purging air from the circuit. It has worked for several years for those I know.
