6.2. Choose a right heat pump unit
(1) Based on the local climate condition, construction features and insulation level,
calculate the required cooling(heating) capacity per square meter.
(2) Conclude the total capacity which will be needed by the construction.
(3) According to the total capacity needed, choose the right model by consulting
the heat.
(4) Pump features as below:
a. Cooling only unit: chilled water outlet temp. at 5-15
℃
, maximum ambient temp.
at 43
℃
.
b. Heating and Cooling unit: for cooling chilled water outlet temp. at 5-15
℃
,
maximum ambient temp. at 43
℃
. For heating, warm water outlet temp. at
9-75
℃
, minimum ambient temp. at -25
℃
.
c. Unit application
Inverter air source water heat pump is used for house, office, hotel, and so
forth, which need heating or cooling separately, with each area needed to
be controlled.
6.3. Installation Method
The heat pump can be installed onto the concrete basement by expansion
screws, or onto a steel frame with rubber feet which can be placed on the
ground or housetop.
Make sure that the unit is placed horizontally.
6.4. Installation Place
a. The unit can be installed on any place outdoor which can carry heavy
machine such as terrace, housetop, ground and so on.
b. The location must have good ventilation.
c. The place is free from heat radiation and other fire flame.
d. A pall is needed in winter to protect the heat pump from snow.
e. There must be not obstacles near the air inlet and outlet of the heat pump.
A place which is free from strong air blowing.
f. There must be water channel around the heat pump to drain the
condensing water. There must be enough space around the unit for
maintenance.
g.
A place which is far away operating or potential ignition sources (for
example: open flames, an operating gas appliance or an operating
electric heater or Electric Spark or hot object)
