Whether the air can drain water in cold weather

If not in use, drain and power off.

1. The normal use of air energy heating units must be in a state of energization; Power failure, water shortage, wrong control cabinet settings, and the unit anti-freezing protection function can not be opened normally, resulting in freezing and damage to the unit equipment, and the air energy heat pump manufacturers have paid maintenance. Basically all air energy heat pump heating units will activate the automatic antifreeze protection function in winter when the outdoor temperature is low.

Reason: The relevant switches of the air energy unit, water pump, control cabinet, etc. must be in the energized state and the automatic water replenishment valve is open, and the relevant valves of the unit system must be in the normal open state before the unit will automatically turn on the anti-freezing function.

2. When the heat pump heating unit is not in use in winter, it should be drained in time.

When the heat pump unit is not running in winter, such as: frequent power outages, unit shutdown at night, winter holidays, and infrequent use of the unit in winter, all the water in the unit, water pump, and outdoor pipeline should be emptied to prevent the unit from freezing and damage.

3. The heat pump heating unit must add antifreeze without draining the water.

According to the specific use of the customer, in the case that the unit is inconvenient to drain and drain in winter and may cut off water and electricity, the entire air energy heat pump heating system must add antifreeze, and must be based on the local minimum temperature as an important parameter for selecting antifreeze.

Yes, it is also a better maintenance method to empty the water of the heat pump unit when it is not used for a long time, and then the unit is powered off.

The air source heat pump has an air energy water heater and an air energy floor heating and air conditioning machine, which should be a household appliance that is frequently used in winter.

Make sure that the basement space is well ventilated, such as an open basement or a ventilation fan with a large capacity in the basement.

The air energy water heater needs to continuously absorb heat from the surrounding air during the working process, if the basement space is closed, the heat in the air in the space is limited, and the air energy water heater cannot work normally.

When placed in the basement, it is necessary to make an installation base of about 20cm for the air energy unit to prevent the air energy unit from causing major failures when the basement is flooded.

As long as the unit is not powered off and the normal power-on standby state is maintained, the air source heat pump will not freeze.

Air source heat pump manufacturers are equipped with a lot of anti-freezing protection functions, which can play a protective role in the power-on standby state.

If the power is cut off for the unit, it will freeze when the ambient temperature is very low.

To ensure the stable operation of the water heater in a low temperature environment, it can automatically enter and exit the chemical tank according to the comprehensive and intelligent judgment of multiple parameters such as outdoor ambient temperature, evaporator fin temperature and unit operation time.

Prevent the water in the system from freezing and freezing the equipment.

Freezing of the waterway system, or damage to the anti-temperature head can cause winter freeze protection.

The main purpose is to prevent the waterway system inside the heat pump unit from freezing and damaging the waterway accessories, pumps, water pipes, etc. when the ambient temperature is below 0 degrees.

How to exchange heat when the heat exchanger is frozen, so it is necessary to defrost and prevent freezing.

It's frozen, how can the water flow? All you need to do is set up a temperature-controlled reverse cycle in the heat pump system.

The pipe is frozen, how do you get water? I see?

Air energy water heaters can be used at low temperatures.

Although the heating efficiency of air energy water heaters will also change due to the change of weather temperature, the attenuation of heating efficiency will not be as obvious as that of solar water heaters.

According to the data, in an environment of 20, the heating energy efficiency of a better air energy water heater can be as high as COP. That is, the water heater consumes 1 kW of heat energy and can "transport" 4 kW of heat energy from the air. When the temperature drops below 0, the heating efficiency of the air energy water heater is usually between.

In contrast, the heating energy efficiency ratio of electric water heaters is only.

It can be seen that even in a low temperature environment, the air energy water heater can be stable for heating. Although the heating efficiency is not as high as in warm weather, it is also less energy-efficient than electric water heaters.

Air energy water heaters can also be used at low temperatures.

1. The air energy water heater works according to the principle of "reverse Carnot", figuratively speaking, the "outdoor unit" compresses the air like a pump to increase the air temperature, and then conducts heat to the indoor water storage tank through a -17 boiling liquid, and then conducts the heat release into the water. Simply put, it absorbs the heat in the air to heat the water, and the air that absorbs the heat is used in the kitchen to solve the stuffiness problem.

2. The higher the ambient temperature, the higher the COP value, and the more significant the energy-saving effect. When the outdoor ambient temperature is below -5, the air energy water heater can still work normally, only its COP value will decrease slightly. At present, many manufacturers specializing in the production of air energy are committed to developing air energy water heaters that adapt to the low temperature and cold air in the north, which can still operate efficiently and stably in low temperature climates.

3. Air energy water heater, also known as "air source heat pump water heater". The "air energy water heater" absorbs the low-temperature heat in the air, vaporizes it through fluorine medium, and then heats up and pressurizes it after compression by the compressor, and then converts it to water for heating through a heat exchanger, and the compressed high-temperature heat energy is used to heat the water temperature. Air energy water heater has the characteristics of high efficiency and energy saving, making the same amount of hot water, which is 4-6 times that of electric water heater, and its average annual thermal efficiency ratio is 4 times that of electric heating, and the utilization energy efficiency is high.

Different models, the operating temperature is different, you should be an ordinary type, there are low temperature type, ultra-low temperature type.

Air energy water heaters can also be used at low temperatures. Many manufacturers specializing in the production of air energy are committed to the development of air energy water heaters that adapt to the low temperature and cold air in the north, which can still operate efficiently and stably in low temperature climates. Bolang's ultra-low temperature air energy water heater can operate efficiently and stably at minus 25 degrees Celsius.

When the subject buys an air energy water heater, he can ask carefully, because the models are different, and the corresponding parameters are also different. You can ask the store which one is suitable for operating in a low temperature environment.

Generally, the night temperature in Harbin can reach minus 30 degrees Celsius in winter, and the outdoor unit of the air conditioner should be started at a low temperature, plus antifreeze oil, and if you are worried, you can add a fence to the outdoor unit to prevent wind and snow. When the weather warms up, the demolition is carried out. Because the outdoor unit needs to be ventilated and refrigerated, the cooling effect will be better.
