The insulation effect of water tank of air source water heater is mainly affected by the following factors:
1.The weather temperature
General manufacturers in the publicity of water tank insulation effect, most are measured in a specific external environment. Therefore, under different ambient temperatures, the insulation effect will be different.
2.Tank liner material
Nowadays, the inner liner of the heat pump water tank on the market is mostly made of 304 stainless steel, with good sealing effect and water storage energy efficiency up to 80%.Secondly, 304 stainless steel insulation tank is made of stainless steel plate or color steel plate as the surface layer, closed-hole flame retardant self-extinguishing polystyrene material plate or polyurethane as the core layer, after the process of optimization and combination, so that the interior and exterior layer together to achieve the best insulation results.
3.Water tank insulation layer material
The air energy tank insulation layer is made of high-density and thickened polyurethane fluorine-free foam, with small heat loss and excellent insulation performance. In the purchase of products, the tank the best insulation layer thickness is between 40 to 50mm, and 360 degrees of all-round insulation function, when the tank capacity is the same, the larger the volume of the tank, the heavier, that the insulation layer is thicker, insulation effect is of course better.
4.Tank temperature package
The water temperature of the tank is mainly controlled by the temperature sensor. The purpose of the temperature packet is to sense changes in temperature and feed back to the main engine control center. The amount and sensitivity of temperature sensitive package are directly related to whether hot water can be provided stably and whether energy saving effect can be achieved.
Focus on the above points, a good water tank achieves twice the result with half the effort.
