When it comes to air energy heat pump, many people may think of the "coal to electricity" project in the north. As we all know, air energy heat pump has become the main equipment of the northern "coal to electricity" project because of its good heating effect, energy saving and environmental protection. But few people know that air energy heat pump has a very good heating effect in winter and a very good cooling effect in summer. For example, hotels in many areas of our country have abandoned the original air conditioning and started to use air energy heat pump refrigeration.

So, is the air energy heat pump refrigeration effective? With this question, the author came to Gui Long Hotel, located in Keji Street, Guiyang. Guilong Hotel is a modern foreign-related tourist hotel invested and built by Guizhou Electric Power Company. The main building is 19 floors high, with various standard rooms, Chinese and Western restaurants, bars and banquet restaurants. It is a local high-end hotel integrating accommodation, catering and business meetings.

Guilong Hotel originally used gas boilers and cooling towers for heating, refrigeration, air conditioning and hot water, but the operation effect has been poor and energy consumption is high. In this case, the hotel decided to upgrade the hot water and heating and cooling system. After many field visits, the hotel finally chose Nurtai air energy water heater and air energy central air conditioner on October 7, 20/KLOC to solve the problems of hotel central air conditioner and domestic hot water in guest rooms.

In winter, the air energy heat pump absorbs the free heat in the air, and a large amount of hot water can be generated with a small amount of electric energy, and then the hot water is transported indoors through pipelines, and the indoor heating is provided through heating terminals; In summer, the air energy heat pump can also produce low-temperature cooling water, and then use the heating end to refrigerate the room. Because the "electricity-heat" conversion mode is not directly used for heating, the heating efficiency is as high as 400%, which is four times that of ordinary electric heaters and electric water heaters.

Hotel staff said in an interview that after more than a year of actual operation, the equipment runs stably, and the hot water in the tenant's body arrives in seconds, and there is hot water when the faucet is turned on. The indoor temperature can reach 30℃ in winter and 24-28℃ in summer. "Because it is a water cycle, the wind blown out by the air energy heat pump is not as violent as that of the air conditioner, and it is softer, similar to the natural wind, but the human body will feel more comfortable and will not easily cause problems such as colds, dry throat and dry skin."
