How to choose qualified defrosting ability standard of air source heat pump

2020-08-31

How to choose and purchase qualified air source heat pump, the defrosting capacity of the unit must reach the standard. In this period, we will talk about the defrosting capacity standard of the unit. First of all, users who have used air source heat pump heating know that the unit will frost when it is running. As for why it will frost, some users may not understand it? Today, I would like to take this opportunity to explain to you. The reason why the air source heat pump can absorb heat from the air is that the evaporation temperature of the refrigerant is very low. When the refrigerant passes through the evaporator, it will absorb the heat in the air. And when the evaporator [learn more]

夏季空调设置多少度更合适

How many degrees of air conditioning is more suitable in summer

2020-08-05

In summer, many people set the cooling temperature of air conditioning at about 20 ℃, or even lower. The temperature difference between indoor and outdoor is too large, just like ice and fire. Is this really good? First of all, let's talk about energy consumption. The setting of air conditioning temperature will affect the power consumption. Generally, the lower the set temperature, the greater the power consumption. The research shows that every two degrees lower the set temperature of air conditioning, the power consumption will increase by about 10% [learn more]

How to lay floor heating more reasonably?

2020-07-21

On the one hand, comfort and energy consumption should be considered when using floor heating. Therefore, if you want to heat well, the floor heating must be paved well. How can the floor heating be laid more reasonably? According to the code for design of heating, ventilation and air conditioning, the water supply temperature of civil buildings is about 35 ~ 50 ℃, and the maximum temperature will not exceed 60 ℃, and the water temperature difference between supply and return should not be greater than 10 ℃. Therefore, it is mentioned in the floor heating design specification that the longest length of the floor heating coil should not exceed 120 meters. If air source or wall is used [learn more]

水地暖和电地暖哪个好

Which is better, water heating or electric heating

2020-07-15

Water floor heating is that the hot water whose temperature is not higher than 60 ℃ is the heat medium, which circulates in the heating pipe under the ground to realize heating. The electric floor heating uses heating cable to convert electric energy into heat energy for heating. Advantages of water and floor heating: first, the gas-fired wall mounted boiler can provide domestic hot water while heating, which can save the cost of purchasing water heater. Secondly, the heating area of water floor heating is large and the heating time is longer. The disadvantage is that water heating will increase the indoor floor height by 5-8 cm, and the preheating start-up time generally needs 3 [learn more]
