The advantages of air heaters are more than disadvantages
Installation of heat pump water heaterAt present, the market of small household air source heat pump water heater mainstream products are very large size, only suitable for installation on the ground and roof, other floors of consumers can only be installed on the balcony. But along with the people to Home Furnishing environmental requirements increase, the balcony of the huge monster, consumers are not willing to accept the _.
. Environmental adaptability problemAir source heat pump water heater with air as heat source, the energy efficiency ratio (COP) and normal working directly with the air source of the temperature, the current design of air source temperature on the market part of air source hot spring water heater to O ~ 40~C (Table 1, and a few other) l=L are rated at 25~C the design parameters of instrument, applies only to the Yangtze River in the south part of. The average temperature in the year is about 10C, and the temperature in winter is generally in the north of the Yangtze River in.10C. The air source heat pump water heater is difficult to achieve the desired energy saving effect. If the temperature to 20~C, the unit can not start, which greatly limits the air source heat pump water heater market space.
In general, the advantages of the air heater can be greater than the disadvantages. At present, it is one of the better heating equipment because of the advantages of energy saving, environmental protection and safety. The utility model solves the problem that the solar energy water heater depends on sunlight to collect heat and the installation is inconvenient. The air heater to heat the heat exchange through the media, does not need the electric heating element in contact with water, there is no danger of leakage of the electric water heater, gas water heater also eliminates the risk of poisoning and explosions, but no fuel heater exhaust emissions caused by air pollution. The greatest advantage of an air heater is "energy saving."". Heat pump water heater is a large free access to air heat, power consumption is only used to move the air compressor energy for energy, so the thermal efficiency is as high as 380%-600%, making the same quantity of water, the use cost of heat pump water heater electric water heater only 1/4, gas water heater 1/3.
3, large size, large occupation space, generally require special computer room.4, the use of the effect in the north, there is no Southern Energy (low temperature, difficult to obtain heat).
The advantages of an air - powered water heater are more than disadvantages, but some disadvantages do exist:1, complex installation, water pipes and more. Longer installation cycle.2, heavy quality, artificial difficult transportation.
