1.Q: What kinds of heat pumps are there? A:According to different heat sources, heat pumps can be divided into three types: air source heat pumps, ground source heat pumps and water source heat pumps;
2.Q: What are the advantages of heat pump units compared with other heating methods? A:The heat supply of the heat pump unit is mainly in: energy saving, environmental protection, safety, no pollution, no waste gas, waste water and waste residue discharge. The overall average operating cost of the heat pump unit only needs 1/4 of the pad heating, and 1/3~1/2 of the fuel oil and gas. , 1/1.5 of the regular sun;
3.Q:The heat pump unit has a heat exchanger. Is it necessary to use electricity during operation? It needs electricity, but electricity is only used to drive the heat pump to absorb heat from the external environment and release the heat energy for heating, unlike conventional electric water heaters that directly heat water, so the electricity consumption is very small;
4.Q:What is the initial investment and payback period? A:The initial investment of a heat pump unit is slightly higher than that of oil and gas boilers, but its special energy-saving effect generally recovers the cost through energy-saving methods within one and a half years; while other heating methods such as boilers generally have a service life of only five years. The service life of the heat pump unit can be as long as fifteen years;
6.Q:Can the heat pump unit operate normally when the temperature is low in winter? A:It can operate normally at low temperature in winter, because the air energy heat pump unit has an intelligent frost function to ensure that the unit can operate stably in a low temperature environment; it can be integrated according to the outdoor ambient temperature, evaporator fin temperature and unit operating time data parameters 、Intelligent judgment to automatically enter and exit the tank;
7.Q:Is it necessary to charge the refrigerant frequently? A:Unnecessary. This is because the air-energy heat pump unit is a sealed part like a refrigerator, and the refrigerant has been safely charged when it is delivered to the user, and there is no need to charge it by itself during use;
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.
10.Q:Does the heat pump unit need to provide a computer room? A:No, the heat pump unit can be placed in a designated place without affecting the beauty of the building, requiring only a small amount of space and no direct lighting; the installation is also very simple, it can be placed in a corner or in the open air, and unmanned operation can be realized. Fully automatic control of constant temperature water supply.
11.Q:Can the heat pump unit use the trough motor? A:Yes, and it is fully automatic control operation. 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.
20.Q:What are the advantages of heat pump products and boilers? A:1. Low operating cost: Compared with gas-fired and oil-fired boilers, it can save an average of 70% of energy throughout the year. Coupled with lower electricity prices and rising fuel prices, the advantages of low operating costs are increasingly prominent; 2. Environmental protection: heat pump products have no combustion emissions, no pollution, and no exhaust emissions, so they are favored by many users; 3. Safe operation: no need to be on duty, compared with fuel boilers, the operation is relatively safe, and the automatic control saves personnel costs; 4. High thermal efficiency: its thermal efficiency is above 300% on average throughout the year, while the thermal efficiency of the boiler will not exceed 100%.
22.Q:What are the characteristics of household heat pump water heaters? A:1. Split design: easy to install 2. Arbitrary combination of water tank hosts: meet individual needs; 3. Pressure-bearing water tank design: water pressure rental, automatic balance of cold and hot water pressure; 4. Microcomputer control: fully automatic operation.
