Q:How does a heat pump work? Why heat pump save energy?
A heat pump simply moves heat from the air and transfers it to the water. A heat pump uses a refrigeration cycle exactly like your refrigerator or air conditioner uses. A proven safe, economical and very trouble-free system. It doesn’t form heat by heat pump itself. It just deliver the heat from air or other source to water. It only needs the transferring of energy. So it need much less energy than electric heater or gas heater. So it can save energy!
Q:What kind of heat exchange does Palm heat pump use?
The heat exchange of Palm swimming pool heat pump is made from titanium, and is virtually impervious to water-chemistry damage.
We use top brand plate heat exchanger for air to water heat pump.
Q:What is the exact temperature range that the unit will work within?
We have two kinds of compressors in swimming pool heat pumps and air to water heat pumps. For big units above 9kw with scroll compressors the lowest working temperature our clients in Europe have recorded is minus 23 deg C (in Finland). In our lab the lowest temperature we can lower to is minus 10 deg C . For small units like 6.3kw with rotary compressor conservatively speaking the lowest working condition is minus -15 deg C.
Q:Is it safe for palm heat pump operation?
With good insulation, electric isolation, we can assure 100% safe operation if the operation is under correct usage according to our instruction manual.
Q:Does the unit ever need draining?
When the air temperature is below 7 deg C or 8 deg C, ice will build up on the evaporator because the moisture in the air will freeze after the heat is absorbed by the cold refrigerant. The unit will automatically defrost the ice by reversing the refrigerant flow. Ice will become water and be drained out of the unit through some holes in the bottom of the cabinet. So if the unit is used in such a low temperature, we need to drain the water.
Q:What are the guarantees on units that you will give us?
As a standard policy we will provide free spare parts with a value equivalent to 1% of the total ordered value. According to the experiences from our clients these free spare parts are beyond enough for maintenance purpose in two years.
In the same time we provide 1 year warranty for any factory fault parts replacement. In urgent, we can send the required parts by DHL to help solving the problem first.
But we don’t cover problem from shipment, wrong installation and incorrect usage of heat pump.
Q:What about the payment terms?
For normal orders we request L/C or 30% prepayment to start production,balance to be paid before delivery. As the order value is below EUR 3000, a small order handling cost of EUR 50 will be charged.
Q:What is the refrigerant gas and does it comply with European regulations?
The gas we are using for European market is R407C OR 410A. It is 100% non-ozone-depleting. We recommand to use R410a for the high efficiency. If you prefer R407C, we can use a rotary compressor from Hitachi which is compatible with R407C gas. We ever produced this unit for some European clients.
Q:Are there any restrictions as to where they can be sited?
There is almost no restriction for installation sites.
Q:Lead times for a container/part container?
The lead time for a container order is 3-5 weeks depending on the availability of the components stock.
Q:Does the unit have a condensation collection tray and drain off point?
There is no drain pan. In the bottom there are two or three drain holes.
