<p>Heat pump water heater is a new type of hot water and heating heat pump products. It is a heating equipment and hot water device that can replace boilers. Compared with traditional solar energy, <a href="https://www.utlaircon.com/heat-pump-water-heater" target="_blank">heat pump water heater</a>s can absorb not only the heat in the air, but also solar energy. The heat pump water heater absorbs heat from the refrigerant temperature difference and compresses the compressor to heat, and then exchanges heat with water, which greatly improves the thermal efficiency and makes full use of new energy. It is a new type of water heater that perfectly combines the respective advantages of electric water heaters and solar water heaters.</p><p><br></p><p><br></p><p><strong>Working characteristics of heat pump products</strong></p><p>The product uses a refrigerant as a medium. The refrigerant has a low vaporization temperature and can be vaporized at -40 ° C. Therefore, there is a temperature difference between it and the outside temperature. The refrigerant absorbs the outside temperature and vaporizes. The refrigerant is heated by compression and becomes high temperature. The high-pressure gas exchanges heat with water through the heat exchanger, then releases the pressure through the expansion valve, returns to the low-temperature and low-pressure liquefaction state, and heats the water in the water tank through the continuous circulation of the refrigerant and heat exchange with the water.</p><p>1, not affected by the environment, available throughout the year;</p><p>2. Outstanding energy saving effect and short payback period;</p><p>3. Environmentally friendly products without any pollution;</p><p>4. Long service life and low operating cost;</p><p>5, safe operation, unmanned operation;</p><p>6. Modular design, easy installation.</p><p><br></p><p><strong>Advantages of heat pumps compared to other products</strong></p><p>1. Wide range of application: The applicable temperature range of the product is -10-40 ℃, and it can be used all day and all year round. It can be continuously heated. Compared with the traditional solar water storage type, heat pump products can continuously heat and continuously supply hot water to meet user needs.</p><p>2. Low operating cost: Compared with conventional solar energy, when the sun is better in spring, summer, and autumn, the operating cost is higher than solar energy, but on rainy days and nights, the thermal efficiency is much higher than that of solar-assisted electric heating. On average throughout the year, the annual energy consumption of conventional solar auxiliary systems is much higher than the total energy consumption of the products.</p><p>3. Convenient installation: The air source heat pump occupies a small space and is similar in appearance to the outdoor unit of an air conditioner. It can be directly connected to an insulated water tank or connected to a heating pipe network. It is suitable for high-rise buildings in large and medium-sized cities. For large central heating problems, the product Is the best choice.</p><p>What are the advantages of heat pump products compared to boilers?</p><p>4. High thermal efficiency: The average thermal efficiency of the product is more than 300% throughout the year, and the thermal efficiency of the boiler will not exceed 100%.</p><p>Low operating costs: Compared with fuel oil and gas boilers, the average annual energy saving is 70%. Coupled with lower electricity prices and rising fuel prices, the advantages of low operating costs are increasingly prominent.</p><p>5. Environmental protection: The heat pump product does not have any combustion emissions. The refrigerant uses environmentally friendly refrigerant R417A, which has zero pollution to the ozone layer and is a better environmentally friendly product.</p><p>6, safe operation, no need to watch: Compared with fuel boiler, the operation is absolutely safe, and fully automatic control, no staff on duty, saving personnel costs.</p><p>7, modular installation, easy to add equipment: the product uses multiple units in parallel installation mode, when the user's water consumption increases, you can add equipment at any time.</p><p><br></p><p><strong>Disadvantages of heat pump products compared to boilers</strong></p><p>Slow heating speed: The heat pump product uses refrigerant as the medium and adopts the compressor compression heating method. Compared with the boiler direct heating mode, the speed is relatively slow.</p><p>Large one-time investment: Compared with fuel oil and gas boilers, when the water consumption is greater than 10 tons, the one-time investment is larger than the boiler.</p><p>There are restrictions on the temperature of the heating water: The temperature of the heat pump water is generally 60 ° C (water source heat pump can reach 80 ° C), and it cannot produce high temperature water or steam above 80 ° C.</p>
