Household Multi-Purpose Water (Ground) Source Heat Pump Units

Specifications

1. The unit transfers renewable energy between the ground and indoor environment so that one KW of electric energy can actually generate 4-5 KW of cooling or heating capacity. The temperature of underground soil is constant around the years. No matter in winter or in summer, the unit can work with high efficiency to save lots of energy. The unit performance does not vary with the environment temperature, and no heat is lost due to frosting in heating operation mode.

2. When working in the cooling mode in summer, the unit can save up to 40%-50% of energy consumption compared with traditional systems. In winter, the unit can save up to 70% of energy. The heat recovery mode can provide free hot water in summer, and provide hot water with a cost that is 50-75% less than the cost of natural gas.

3. Among small-sized multi-purpose air conditioning systems, units of this series are most energy efficient, reducing the usage of boilers and the emission of carbon dioxide and helping to maintain a green environment

4. Constant hot water capacity provides hot water up to 70°C (no electric heater). The water temperature can also be set to an optimal temperature (for example, 40°C) without mixing hot and cold water. The central hot water system features an automatic cleaning device so that hot water is comfortable and clean.

5. A heat pump compressor is used and water and electricity are separated. The unit causes no contamination to the air or environment, and eliminates risks of electric shock from common electric heaters and gas leakage, dry burning, and poisoning risks from gas heater. A pressure bearing water tank with a large capacity is used, eliminating defects such as unable to be lit due to water pressure fluctuations in gas heaters.

6. A controller with a large LCD screen is provided to monitor the water temperature in real time. Users can also set a program to preheat the water.

7. Flexible and smart switches allow users to set hot water and heating programs as required. Using an electronic control technique, the controller can monitor the inlet/outlet water temperature; compressor, pump, and hot water status; and faults and alarms in real time.

8. By connecting units through RS485 to USB modules or the Ethernet, units in different houses or communities can be centrally controlled by a local computer or by a remote computer on the Internet.

9. By connecting units to a telephone module through RS485, users can set temperature and operation mode; turn a unit on/off, and execute other intelligent control such as receiving alarms on telephones remotely.

10. The unit features a leading-edge design combining central household air conditioning, floor heating, and central hot water systems. Advanced heat recovery techniques ensure that heat is recovered to the maximum, and that hot water is instantly available. Compared with traditional household central air conditioning systems, units of this series do not need defrosting which degrades the capacity, and does not start/stop frequently. Water and electricity are separated to eliminate the risk of electric shock. No harmful gas is eliminated to ensure user safety.

11. The unit provides cooling, heating, and free hot water at the same time. Waster heat generated during the cooling process is recovered to make hot water for free up to 70°C around the clock without any auxiliary elec
