How to calculate the buffer tank capacity?[ 11-21 15:49 ]
The minimum water volume is 12L/KW.If you install 15KW heat pump, the mini. buffer tank capacity is equal to 12*15=180L.There is no limit for the maximum, to some extent, the larger, the better.
Why the parameter could not make change?[ 11-21 15:49 ]
HISEER heat pumps adopt with Siemens controller.When the heat pump is running, it is dangerous to change some of the key running data or change something by mistake.
What is the advantage of changeable temperature control ?[ 11-21 15:49 ]
HISEER heat pumps adopt with Siemens or Carel controller.There are fixed temperature control and changeable temperature control.When SF04=1, the heat pump will be controlled by outdoor temperature, indoor temperature and the heating compensation coefficient curve factor. Any of the 3 factors changes, the control temperature will verify accordingly.
Why a buffer tank is required ?[ 11-21 15:48 ]
A buffer tank is recommended to ensure a trouble free heat pump operation.When a buffer tank is installed, the heating or cooling system will absorb energy from the buffer tank first to save energy consumption.
Why water flow alarm usually blinks for newly installed heat pump?[ 11-21 15:47 ]
For newly installed heat pump, if there is air in the heat pump system, water flow alarm will usually blink, the heat pump could not be started.Totally vacuum the heat pump and the water flow volume reach the standard requirement, the water flow alarm will disappear.
Why there is no hot water for my heat pump?[ 11-21 15:44 ]
HISEER heat pumps adopt with Siemens or Carel controller.The hot water function is controlled by hot water switch (A1-A2).When hot water switch A1-A2 is bridged, the hot water function is activated.
Why the heat pump (triple phase) could not be started after B1-B2 is bridged ?[ 11-21 15:44 ]
HISEER heat pump with triple phase adopt with a phase protector, if the phase is not correctly connected, the heat pump could not be started.The correct three phase connection is as follows:
Why the heat pump could not be started after installation?[ 11-21 15:42 ]
HISEER heat pumps adopt with Siemens or Carel controller.When SF14=0, the heat pump will be ON/OFF by A/C switch (B1-B2).The heat pump will be started when B1-B2 is bridged.The heat pump will be stopped when B1-B2 is disconnected.
Inside a Water Heater[ 10-19 12:12 ]

How is Freon utilized in air conditioning?[ 10-19 11:57 ]
In a similar way to how your refrigerator manages to stays cold, but minus the insulated box. A nonflammable gas, known as Freon, undergoes an evaporation process again and again within most refrigerators in order to keep the temperature low. The same cycle is used for air conditioners.
Hiseer news: geothermal unit[ 10-19 11:54 ]
The most common type of geo-thermal unit for homes is the closed-loop system. Polyethylene pipes are buried under the ground, either vertically like a well or horizontally in three- to six-foot trenches.
Hiseer news: Energy Efficient Cooling Systems[ 10-19 11:52 ]
Because of the rising costs of electricity and a growing trend to "go green," more people are turning to alternative cooling methods to spare their pocketbooks and the environment. Big businesses are even jumping on board in an effort to improve their public image and lower their overhead.
Hiseer news: BTU and EER[ 10-19 11:49 ]
Most air conditioners have their capacity rated in British thermal units (Btu). A Btu is the amount of heat necessary to raise the temperature of 1 pound (0.45 kilograms) of water one degree Fahrenheit (0.56 degrees Celsius).
Chilled-water and Cooling-tower AC Units[ 10-19 11:46 ]
Although standard air conditioners are very popular, they can use a lot of energy and generate quite a bit of heat. For large installations like office buildings, air handling and conditioning is sometimes managed a little differently.
