3 Factors to Consider when Choosing a Ground Source Heat Pump
Ground source heat pumps are widely used as a new type of energy-saving and environmentally-friendly air conditioner. There is a big difference between the ground source heat pump system and traditional air conditioning design and installation. Not every household user is suitable for installing a ground source heat pump system. When choosing a ground source heat pump system, the following factors must be considered.
Outdoor grilling area
The ground source heat pump exchanges heat with the soil through outdoor well drilling. According to the national standard GB 50366-2005, the distance between underground wells is generally 4.5m (the larger the distance, the better the effect), and the construction area of 300 square meters requires at least 80 square meters to drill wells.
The construction area of 400m2 requires at least the well drilling area of 110m2 well drilling area, empirical calculation of well drilling area and the building area is about 1:1; take townhouse as an example: If the well drilling area is too small, it will cause the effect of air conditioning to decrease year by year, and the system will not function normally after 5 or 6 years.
Impact of improper installation
(1) Compared with fluorine machines, the cooling and heating speed of the ground source heat pump is relatively slow. (Simply speaking, because the fluorine machine is a primary heat exchange; the water machine is a secondary heat exchange, and the air supply temperature of the water machine is 3 to 4 degrees higher than that of the fluorine machine.)
(2) The pipeline has certain hidden dangers of water leakage. (Because it is impossible for water pipes to achieve a leakage pressure holding test of about 40 kg like copper pipes.)
(3) The principle of refrigeration is different, which causes the indoor unit size and noise of the ground source heat pump to be larger than that of the fluorine machine, the general noise should be 5～10dB(A), and the height of the internal machine should be 3～5cm.
(4) The maintenance cost will be higher in the future. (Because whether the installation pipeline is connected with PPR pipe or steel pipe or copper pipe, the pipeline must be cleaned and maintained regularly, otherwise, the use effect will become worse and the power consumption will be caused by the decrease of the water flow in the system. Increase in volume.)
The energy-saving of the ground source heat pump system has a lot to do with our daily usage habits and the number of residents people.
If there are a lot of resident people and you are used to turning on most of the internal machines at the same time, the ground source heat pump system is more energy-saving, because ground source heat pumps are generally fixed-frequency compressors. The water pumps are generally running 24 hours a day and consume the same power no matter how many internal units are turned on.
One of the most important criteria for selecting a ground source heat pump system is the rate of return on investment. If the initial cost increase is too high, and the later cost recovery is not ideal, then choosing a ground source heat pump system is of little significance. If the ground source heat pump system has high operating efficiency, low cost, and high return on investment in the later period, you can choose a ground source heat pump.
