How deep need for closed loop geothermal system?

2018-08-24T15:42:00+08:00Categories: Knowledge base|

How deep trench of the horizontal loop when install closed loop geothermal system? You may need to get out what is the soil temp after coldest winter passed, if very low, the deeper, the better. Shallow loops need to place more longer pipes. Normally trenches deeper than 1.5m, and length for several thousand m, with a backhoe or chain trencher, then pipe laid in the trench and backfilled. A typical horizontal ground loop will be 30-50m [...]

What can we do when air to water heat pump not working in cold weather?

2018-08-26T16:53:18+08:00Categories: Knowledge base|

Although the air to water heaters (heat pump water heaters) keep high-speed upward trend development in the market, it still inevitably bring some users doubts and confusion. Air source heat pump hot water temperature rise slow often makes the user's doubt its energy-saving condition. With fault, the consumed heating power of an air source heat pump would not much lower than traditional water heaters. But from rigorous testing at laboratory, air to water heaters energy-saving [...]

The heat pump is running but outlet water temperature can’t meet requirement.

2018-06-18T14:43:20+08:00Categories: Knowledge base|

The heat pump is running but outlet water temperature can’t meet requirement. For the outlet water temperature, a normal air source heat pump can produce hot water of 55℃ to 60℃ at most ambient conditions, but at very low ambient temp conditions, it outlet water temp difficult to run more than 50℃. If indoor unit combined with radiator, which is 1950s coal-fired boiler companion, now still in the countryside using, the outlet water temp of [...]

How to Add Freon to Your Heat Pump in Winter

2018-06-18T12:54:03+08:00Categories: Knowledge base|

Instructions 1.Connect the low pressure side of the manifold gauge, the blue hose, to the low pressure port located on the suction side of the compressor, not the suction line as you would do with a standard air conditioning unit or a heat pump operating in the summer. Heat pumps will have an additional port just for this purpose located between the two refrigerant lines. Remember, heat pumps reverse the pump direction in the winter. [...]

Heat pump vs air conditioner

2018-06-18T19:58:11+08:00Categories: Knowledge base|

Heat pump vs AC, what is the difference? First, an air conditioner is a type of heat pump. It “pumps” heat from the inside of a building to the outside to cool the indoor space. The critical difference between the heat pump vs AC is that an air conditioner is only useful for cooling, a heat pump can switch modes and move heat from the outside into the building,switching between modes makes a heat pump [...]

The heart of a heat pump

2018-06-18T13:04:27+08:00Categories: Knowledge base|

The heart of a Heat Pump is the compressor, which takes low pressure refrigerant gas and squeezes it, raising the pressure and temperature in the process. This hot gas then condenses at the high pressure giving off large amounts of heat for a relatively small amount of electricity to power the compressor's motor. The more efficiently the gas is compressed, the higher the COP of the heat pump. Both piston and scroll compressor designs have [...]

Radiant underfloor heating? heat pump underfloor heating!

2018-06-18T14:42:07+08:00Categories: Knowledge base|

Radiant electric underfloor heating or heat pump underfloor heating? Underfloor heating is the most luxurious form of heating as its radiant heat is evenly distributed throughout the room—wall to wall, floor to ceiling—right where you feel it the most. Hard floor surfaces are warm to the touch and with no air being blown around it is totally silent. What’s more, the system is totally hidden from view and, unlike radiators or surface mounted heat pumps, [...]

How to do when winter rainy days clothes hard to dry?

2018-06-18T12:53:53+08:00Categories: Knowledge base|

Winter is cold, and with unexpected rain, added the chill feeling, but more troublesome is that the winter clothes are thick, once rains, take more than one week to dry, Winter we always dress more and wash more, even the drying places is not enough. Especially with small baby's family, need to wash a lot of baby’s clothes. In this case, we will need a high temperature heat pump dryer, which is now widely used [...]

What is a Passive House?

2018-06-18T14:44:19+08:00Categories: Knowledge base|

“Passive hause” is a German standard for extremely energy efficient building construction. It is built to always provide a comfortable interior climate always maintained between 16-24oC without a traditional heating system or active cooling. The heat storage capacity of the building construction ensures, even during longer phases of absence and lower heat gains, that interior temperatures don’t decline drastically or rise extremely high when solar gains are high. A combination of the sun, its occupants, [...]
