8.Q:Why are heat pump water heaters more effective than electric water heaters?
A:The general heating method is to directly use energy to heat water. The energy efficiency of electric water heaters is 95% and that of natural gas is 75%. The heat pump unit uses electricity to drive the compressor instead of directly heating water. The heat energy needs to be adjusted according to the environment. Certainly;
9.Q:Is the heat pump a solar product?
A:In a broad sense, yes, but heat pumps are essentially different from conventional solar products, which are mainly reflected in different working principles; conventional solar products rely on direct sunlight or radiation to achieve heating effects; while heat pump units are mainly Absorb ambient heat to achieve heating effect.

The air energy heat pump unit is designed with a corresponding insulation water tank according to the user’s hot water consumption; the insulation water tank has a good insulation effect, and the air energy heat pump unit has a timing start and stop function In this way, hot water can be produced and stored in the insulated water tank when the electricity price is low.
12.Q:If multiple heat pumps are used, will a problem with one of them affect the entire system?
A:No effect, the air energy heat pump has a modular function and is connected to the grid for operation, and each heat pump unit can be controlled separately; even if one of them has a problem, it will not affect the normal operation of other units during maintenance;
13.Q:How to match each type of heat pump water tank?
A:Because the output load of the heat pump unit is relatively small, the production speed of hot water is relatively slow.
14.Q:How to correctly understand “heat pump”?
A:To give a very simple example, a car can consume a few liters of gasoline to transport a few tons of goods from the location to the destination; the heat pump unit can absorb heat from nature and then use the heat pump to transport “electricity to drive the heat pump” to obtain heat that can be used for production and life.
15.Q:Is the heat pump unit stable during operation?
A:It is very stable and reliable during operation. The air-energy heat pump is equipped with high and low pressure protection, antifreeze protection in winter, high outlet water temperature protection, insufficient water flow temperature difference protection, water flow switch protection, excessive exhaust temperature protection and compressor operation and shutdown delay. Protect.
16.Q:How to choose a domestic heat pump water heater?
A:The water tank of the heat pump water heater is determined according to the actual water consumption of the user in one day. Under the conditions acceptable to the user, it is recommended that the user choose a large model water tank. General family 1-2 people, with 150 or 200L water tank (199L/person); 3-4 people, with 200 or 2x150L water tank (80L/person); 5-6 people, with 300 or 2x200L water tank (70L/person).
17.Q:What is the general power consumption of the air energy heat pump unit?
A:The thermal efficiency of the air energy heat pump unit is generally 300%-500%. Calculated with a temperature rise of 40°C, the production of one ton of hot water is about 9-15 degrees, while the general electric heating method consumes 52 degrees.
18.Q:Why does absorbing thermal energy from the environment make the heat pump more efficient?
A:That’s because a small amount of electricity is required to run a heat pump, which can transfer three times as much thermal energy from the environment; then using that thermal energy to heat water can achieve thermal efficiencies of over 300 percent.
19.Q:What is the principle of the heat pump unit for heating?
A:A heat-absorbing medium-refrigerant is specially installed in the heat pump unit equipment, which is lower than minus 20 degrees Celsius in the liquefied state, and there is a temperature difference with the outside temperature. Therefore, the refrigerant can absorb external heat energy, evaporate and vaporize in the evaporator, and increase the temperature of the refrigerant through the operation of the compressor in the heat pump unit; then the refrigerant is converted from the vaporized state to the liquefied state through the condenser.
In the process of conversion, a large amount of heat is released, which is transferred to the reserve water in the water tank to increase the water temperature; thus achieving the purpose of making hot water, which is also the unique feature of this product.
