Product Features

1. High efficiency, energy saving, low operating costs;

Sunbright high-efficiency water-source heat pumps use R410 low-temperature eco-friendly refrigerant and highly efficient, dirt-resistant, anti-corrosion titanium tube heat exchangers.

High energy efficiency ratio: COP value above 4.3 in winter; EER value above 5.0 in summer.

Winter operating costs: 1/2 of air-source heat pump operating costs; compared to electric boilers, operating costs are less than 1/4 of electric boilers;

Compared to natural gas boilers, operating costs are 1/3 of natural gas boilers (natural gas price: 3.23 yuan/m3, electricity price: 0.55 yuan/kWh).

Summer operating costs: Compared to household split air conditioners or air-cooled units, operating costs are 1/2 of household split air conditioners or air-cooled units.

2. Green and eco-friendly;

High-efficiency water-source heat pump systems produce no exhaust gas, waste residue, or wastewater discharge, and noise is reduced by 40% compared to air-source heat pumps.

3. Easy installation, compact size;

Can be installed indoors, outdoors, or in basements. The installation volume of the unit is 40% smaller than air-source heat pumps, can be stacked for installation, and occupies minimal space.

4. Strong system reliability;

The unit operates stably and is unaffected by changes in ambient temperature. Even in cold winters, heating capacity does not degrade.

5. Low maintenance costs;

No maintenance costs for cooling towers or fans, and no maintenance process for defrosting air-source heat pumps in winter. Maintenance costs are low.

6. Long service life;

Service life of over 15 years, longer than ordinary air conditioning systems and heating equipment.

7. Compared to water-source heat pumps;

No reinjection issues, no consumption or waste of a single drop of groundwater resources.

8. Compared to ordinary ground-source heat pumps;

Solves the problems of high system cost and large footprint: system cost is only 1/5–1/10 of the original, and footprint is only 1/10–1/1000 of the original.

9. Compared to air-source heat pumps;

Solves the problems of high initial installation costs, unstable operation, high noise, and high operating costs: unit initial installation costs reduced by 30%, noise does not exceed 45 decibels, winter operating costs reduced by 50%, summer operating costs reduced by 70%.

10. Compared to ordinary central air conditioning units;

Dual-purpose for cooling and heating (ordinary central air conditioning units only provide cooling in summer), with low operating costs. Summer operating costs are 1/2 of air-cooled unit operating costs.

Sunbright High-Efficiency Water-Source Heat Pump System Working Principle:

Based on the reverse Carnot cycle principle, it uses electrical energy to drive the system, extracting "heat" from surface soil or water via refrigerant heat exchange for winter heating. In summer: it extracts heat from indoors to achieve air conditioning cooling and releases thermal energy into the soil or surface water, enabling cross-seasonal thermal energy recycling.

The high-efficiency water-source heat pump unit mainly consists of a compressor, condenser, expansion valve, evaporator, refrigerant, piping, electrical control components, and other parts. During operation, the compressor inhales low-temperature, low-pressure refrigerant vapor generated in the evaporator, maintaining low pressure in the evaporator and creating conditions for the refrigerant liquid to continuously absorb heat from the coolant and boil at low temperatures. The inhaled vapor is compressed, increasing its temperature and pressure, creating conditions for the refrigerant to liquefy. The high-temperature, high-pressure vapor is discharged into the condenser, where, under constant pressure, it is cooled by the cooling medium (water), releases heat, lowers temperature, and further condenses into liquid, which is discharged from the condenser. High-pressure refrigerant liquid passes through the expansion valve, where resistance causes a pressure drop, leading to partial vaporization of the refrigerant liquid, absorbing latent heat of vaporization, and reducing its own temperature, becoming low-temperature, low-pressure wet vapor that enters the evaporator. In the evaporator, the refrigerant liquid absorbs heat from the coolant (water) (i.e., producing cooling capacity) and vaporizes under constant pressure. The resulting low-pressure, low-temperature vapor is again inhaled by the compressor, repeating this cyclic process.
