Do you know the difference between AIR source heat pump and the Air cooled water chiller?
Details
"Air conditioning" means "air conditioning", which includes a series of functions such as refrigeration / heating / dehumidification / purification. However, in the eyes of most consumers, air conditioning has been completely equivalent to "refrigeration" products in the market, so it is also "air conditioning". In the communication, its meaning has changed quietly. When we discuss the air source heat pump and the air-cooled chiller and water heater, we find that they both belong to the name in the academic sense, which means that from the technical point of view, we can make it clear. First of all, it is certain that air source heat pump and air-cooled chiller and water heater are not the same kind of things. Otherwise, academic experts don't need to take two different names to confuse themselves. Many people are confused about these two kinds of products because we start from the appearance when we recognize things, just as we judge people, we always forget the essence under the appearance The original meaning of air-cooled (hot) water unit is air-cooled chiller, and "heat" was added later. Therefore, for this unit, "heat" is a very secondary function. In the word "air source heat pump", the two words "source" and "heat pump" are emphasized. Therefore, the function of "heat" is the core point of air source heat pump, which emphasizes obtaining heat from the air. All the differences between the two are caused by this! Maybe some people will say that the function of "heat" is the core of air source heat pump,Air cooled water chiller and water heater emphasize "cold" and "hot", while air source heat pump emphasizes "hot" and "cold". They all need cooling and heating, isn't it the same? The answer is no. In fact, for a set of steam compressor units, due to the completely different refrigeration and heating conditions and functions, the design of this unit must have a standard working condition and function. Under this standard, the application of other working conditions and functions should be taken into account. There can only be one design standard, either refrigeration condition or heating condition. It is almost impossible to say that after a set of unit is designed and manufactured, the refrigeration performance is the best and the heating performance is also the best (the best here is the comparison between the unit itself and itself). Therefore, the difference of function will inevitably lead to the difference of design concept. That is to say, for an air source heat pump unit, all the parameters of the system are to meet the heating performance first, and then consider the refrigeration performance. For a typhoon chiller and water heater unit, all parameters of the system are to meet the refrigeration performance first, and then take into account the heating performance.
