Optimal selection of professional swimming pool constant
temperature heat pump equipment
Automatic heating control, special heating constant temperature for
swimming pool, help you save more than 80% of heating costs
Special heating for swimming pool, automatic digital display
temperature
The swimming pool thermostatic heat pump is completely separated
from water and electricity. Separation design. High-voltage
shutdown protection, over-temperature protection and water flow,
current protection, etc. Eliminates flammable/explosive and gas
poisoning of ordinary heat pump units
High efficiency and energy saving Constant temperature heating
Higher energy efficiency ratio, the highest COP can reach 3.9.
Driven by electric energy, there is no emission and pollution, and
it is green and environmentally friendly. Long service life, low
maintenance cost
Four seasons, all-day, cyclic operation, all-weather operation
throughout the year, not affected by bad weather such as night,
cloudy, rain and snow. Provide comfortable hot water and stabilize
the suitable temperature.
Automatic constant temperature adjustment, small temperature
difference, intelligent calibration of constant water temperature,
automatic water replenishment, and solve the problem of hot and
cold water
Strive to be the best in terms of core components and manufacturing
processes. It can be widely used in hotels, villas, holiday
resorts, fitness, saunas, bathing centers, stadiums, schools,
factories, breeding bases, etc., which need to provide a large
amount of hot water. place
Precautions and common problems
It is recommended to be installed outdoors and well ventilated
1. The air source heat pump should be a base, because it will be
frosted in winter, and water will flow out during the defrosting
process and need to be drained.
If it must be installed in room air, it must be well ventilated, or
have a larger space, and there must be heating for heat exchange
2. Special attention should be paid to:
The water flow must be fully matched, otherwise the water flow will
be protected and the heat pump cannot be started. The return pipe
should be as large as possible. For example, the heat pump has a
pipe diameter of 1.5", and the inlet pipe is recommended to be 2"
and bigger.
