Air source heat pump new market - infant swimming pool hot water supply

Infant swimming pool more common in cities, people’s living standards gradually increased after an emerging product. Swimming pool has a professional swimming pool, you can provide just enough comfort for the newborn child’s hot water swimming experience. The opening of a family of infants and young children’s swimming pool, but also to the relevant industrial chain began to be active. Among them, the air source heat pump hot water market as an important device, also ushered in the new development opportunities.

Air-source heat pump by a lot of infants and young children’s swimming pool owner to fancy, there are several reasons, the first to say is safe. Normally, equipment for supplying hot water to buildings includes oil-fired boilers and coal-fired boilers. Both of these facilities have an open flame during the heating process, posing a potential safety hazard. For infants and young children’s swimming pool this place has a demanding safety requirements, it is not so suitable.

Air source heat pump driven by electric energy, through the refrigerant absorbs heat in the air to produce hot water. Heating process, do not consume any fuel, natural gas, the flame does not appear to burn, so completely eliminate fire hazards. Heat pump heat exchanger also uses water and electricity separation design, but also reduce the probability of leakage of equipment at the root causes, has become the safe patron saint of the babies.

Then analyze the cost of air-source heat pump heating costs. In Guangzhou, there are quite a few cases of using the air source heat pump to heat the baby swimming pool. The author has obtained a detailed data from the list below. A baby swimming pool installed a 5P air source hot water unit. The installation cost of the project is about 20,000 yuan or so, which is about 8,000 yuan higher than the nearby swimming pool that uses oil-fired boiler heating.

However, in the subsequent use, the energy-saving effect of air-source heat pump gradually highlights. The use of oil-fired boiler heating, daily consumption of about 30L of fuel consumption, oil prices at 6.7 yuan / liter basis, the daily operation cost of oil-fired boilers over 200 yuan. Air source heat pump, as it is taken from the air, the daily power consumption is only about 20 kWh, commercial electricity price of 1.5 yuan / kWh, count down, heat pump daily operating costs only tens of dollars, far below the oil-fired boiler .

With the increase of newborns, air source heat pumps will also come one after another in the next few years in the market a small outbreak.

Ground source heat pump and air source heat pump how to choose? What's the difference?

Ground source heat pump and air source heat pump popularity, but also so many users in the choice of entangled, do not know which one is good? Do not know how to choose?

Both ground source heat pump and air source heat pump are energy saving and environmental protection heating and cooling equipment systems, which are all systems that utilize advanced heat pump technology for energy conversion. However, their conversion methods are not the same: ground source heat pump is the use of soil heat for energy conversion , While the air source heat pump is the use of air source heat pump technology for energy conversion, but there are some differences between the two.

1. Ground source heat pump more energy efficient, but need to dig wells, the installation needs to have the conditions of drilling, the initial cost will be higher, suitable for villas, schools and other places.
2. Air source heat pump does not require drilling, just need air on it, covers an area of space is relatively small, suitable for high-rise buildings.
3. Ground source heat pump host, end and underground buried pipe systems, and air-source heat pump only the host and the end, the relative operation is relatively simple.
4. Ground source heat pump than the air source heat pump temperature stability, ground source heat pump is the use of soil heat transfer method, the soil temperature is relatively constant throughout the year, and the air source heat pump is the use of air.

Both ground-source heat pump and air-source heat pump are energy-saving and environment-friendly energy systems, each with its own advantages. Users should choose suitable and suitable ones according to their actual conditions to achieve the maximum effect.

What are the two installations or trigeneration of air source heat pump

Air source heat pump technology from Europe, which has been widely applied in developed regions such as Europe, the United States and Janpan. Air source heat pump technology is mature, there are many kinds products. But the development of air source heat pump in China but also more than 10 years of time, nearly two years with governance environment pollution, promote clean energy use, air source heat pump products slowly into the public eye, in 2016, the north of China coal to electricity, greatly promoted the popularization of air source heat pump heating.  

Air source heat pump in China has experienced the hot water, heating, cooling, drying and so on several stages, the specific representative of products for, air source water heater, air source two installations, air source trigeneration, air source drying equipment etc. Air source water heater and air source drying equipment from the literal can understand what product, what effect, but what exactly are the two installations and trigeneration ?

We all know the working principle of air source heat pump is refrigerant obsorption of low temperature heat in the air, through the compressor compressed into high-temperature heat, hot water, high temperature heat can be converted to again so it is the application of air source heat pump is the most primary air source water heater, direct and simple technical requirements is low. Air source heat pump technology to demand higher belongs to heating, cooling and drying field. In order to realize heating of the air source, in the end usually use floor heating system. To achieve refrigeration, air source in the end usually use central air conditioning system. 

So two installations is the use of a set of air source heat pump system, provide hot water, heating or provide heating, cooling, two functions, so the air source two installations are collectively, floor heating and air conditioning or , floor heating and hot water machine. The trgeneration is air conditioning+floor heating + hot water machine. Then many people will ask that why can’t two installations are refrigeration +hot water? This is from the design concept for the air source heat pump, at the beginning of the design but with the development of air source heat pump technology, comprehensive user’s demand to the refrigeration, the consolidation of refrigeration in the air source heat pump system, the function of the refrigeration is belong to the second and third. It’s like at the beginning of the air conditioning design is used fro cooling,k with the air conditioning technology development, can also provide heating, air conditioning refrigeration powerfull effect not only.

Air source heat pump units of defrosting method

With development of the trend of environmental protection and energy saving, the use of air source heat pump is gradually increasing, because in case temperature, air source heat pump in use process to frost phenomenon, affecting the performance of air source heat pump, today the air source heat pump defrosting methods to share with you. 

1. Stop frost: air source heat pump heat exchanger surface frost layer forms, too thick frost layer can reduce heating efficiency of the unit and increase power consumption, unit in this case the runtime also particularly prone to failure. Stop frost is the most convenient forms of air source heat pump units frost simple a way.

2. Reverse cycle defrost: switch the four-way reversing valve, which changes the flow of refrigerant, so as to achieve the effect of evaporator and condenser role exchange, close the fan, through the refrigerant of heat and the effect of the frost. This method is the most common of all the way to frost, frost process faster, improve the efficiency of the air source heat pump units of frost.

3. The hot gas bypass defrosting: open the hot gas bypass valve, turn off the fan, compressor exhaust will arrive through the hot gas bypass valve of liquid receiver, finally into the air cooled heat exchanger of defrosting.This way of defrosting effect is obvious and can not only shorten the time of frost. 

Timely to frost, air source heat pump units can not only improve the heating efficiency of the unit, also can reduce the damage to the equipment, can effectively increases the service life of air source heat pump units. Select the correct defrosting method can not only reduce the frost time, improve the working performance of the unit.

Air source heat pump floor heating and radiator which is better

With the constant change of the weather is cold, people also particular concern for heating, mostly to install heating system at present, the most popular in the market is the air source heat pump heating floor heating and radiator heating, for above two hot heating ways which one is better, here is to analyze the advantages and disadvantages of them and so that everyone can have a full understanding.

Air source heat pump floor heating and radiator, by contrast, both the running principle of basic similar, is through the hot gas send out to realize the rise of temperature, finish heating, but still exist between different, installation of floor heating is in installation is needed before operation, the building is decorated after renovation is difficult when installation, quantity is big, time is longer, so after the installation is not recommended, and the radiator before decorate and decorate after all its installation will not cause any influence, less construction difficulty, installation time is short, convenient and simple. 

Air source heat pump installation, the method is relatively hidden, will not take up too much space, will not affect the beautiful house, and it has obvious advantage that the ordinary floor heating, heating faster when using, heat evenly, comfortable is extremely strong, energy saving effect is remarkable, and the radiator need to choose suitable location to install, will occupy a certain space, so that air source heat pump heating floor had a good choice. 

Air source heat pump floor heating is buried in the ground, is by raising the temperature of low temperature hot water, transfer heat from underground into the air, as a result, the heat from bottom upm confirms to the principle of keeping in good health, and the heat evenly inside the air, the temperature difference is small, comfortable and reliable. Radiator is only a fraction of the concentrated heat is to heat the air around first, and then achieve the purpose of heating by air convection heat transfer, this way of thermal comfort is relatively poor.

For now, the air source heat pump heating is a clean way of heating, with the continuous development of air source heat pump, remarkable achievements in the field of heating, and is used by more and more people, so will gradually become the first choice for heating.

Another advantage is use of air source heat pump running costs are relatively low, it is compared with other heating way, by contrast, it is also in favor of the heating way of the human body health.
