Summary of contents: China has a vast territory, large latitude spans between North and South, and a large temperature difference between South and North in winter. The huge temperature difference also leads to differences in the product design concepts of heat pump companies in the two places. This difference is mainly reflected in defrosting. Southern air heat pump manufacturers do not need to consider the problem of defrosting when designing, and the manufacturing cost can also be reduced. This is the key to the price advantage of the southern enterprises. Therefore, the northern heat pump water heater market has become the focus of heat pump technology.

However, the fact that defrosting does not directly lead to the use of products of some southern enterprises in the south is still good. Once problems are encountered in the use of the North, there are constant problems. In the design of the northern enterprises, we must take into account the defrosting, and thus greatly reduce the probability of problems from the source. Over time, in the minds of the public, we have formed the notion that Nanbu is inferior to Beibu. Climate differences lead to product differences. Most southern companies have realized this and have made targeted improvements. Competition in the northern markets will also become more intense.

Take the heating and hot water machine with wide demand in the north, this product has been demonstrated in the concept of multi-function at the beginning of development, but from the actual use effect, it is far from the theoretical value. It is understood that the actual application of the integrated machine for the collection of heating and hot water in the northern region is very unsatisfactory. The actual application of the effect is to use a heat pump or a single heating, or a single system of hot water, if the two combined into one, the current technology, the more difficult point.

For the heat pump water heater market in the north, it is mainly to seize the market share of the boiler. If the heating and hot water heating cannot be fully combined, its advantage will be lost by half. Therefore, for the current technology of heat pump water heaters, there are still many areas that need improvement and improvement. The extension market must first produce products and produce products that meet the needs of the general public. This is the primary condition for opening up the future.

To a certain extent, the core technology of professional compressors allows heat pump water heaters to break the application restrictions of the northern market and expand the scope of application. However, from another perspective, the application of heat pump water heaters in the northern market in the project is not a simple product issue, but a long-term system running-in and matching. It is just like a person when he has a healthy and active beating heart, but also has the ability to smoothly transport its blood, so that it can run steadily for a long time. Therefore, the technical efforts made by companies in the northern market are far from enough.
