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.
