As the national "13th Five-Year Plan" is coming to an end, on October 29, 2020, the Central Committee of the Communist Party of China formulated the "Proposals for the Fourteenth Five-Year Plan for National Economic and Social Development and the 2035 Long-Term Goals". A five-year development indicates a new direction.
in the "14th Five-Year Plan" especially emphasizes the need to promote green development and promote the harmonious coexistence of man and nature. As "green economy" has become the theme of global development, my country has proposed to achieve the turning point of China's carbon emissions by 2030, which means that China's green, low-carbon and energy-saving industries will usher in a spurt of growth. The country will continue to put forward higher requirements in terms of promoting energy conservation, emission reduction, technological innovation, and accelerating the adjustment of energy structure. Relying on the integrated energy system to develop integrated energy services has also become the first choice of many users.
1. Energy-saving highlights and pain points of air source heat pumps
heat pump technology is a new energy technology that has attracted worldwide attention in recent years. It can be divided into air energy, solar energy, and water source heat pumps. It is widely used in major central heating Water system heating field. Compared with traditional pure electric heating, the air source heat pump saves more than 50% energy. Its energy saving principle is essentially a heat "transportation" device. When the
air source heat pump is working, it first inputs 1 part of electric energy to drive the compressor to do work, and then absorbs a large amount of heat energy from the ambient temperature, and releases heat in the condenser through the refrigerant circulation system. It is precisely because of the existence of the "law of conservation of energy" that the 1 share of electric energy input to the compressor can always be converted into 1 share of heat energy, and the large amount of heat energy absorbed from the external environment becomes an additional harvest.
Compared with traditional electric heating, the energy saving efficiency of air source heat pump is much higher than that of pure electric heating. However, if the seemingly energy-saving heat pump is not used well, its energy-saving effect will be greatly reduced.
Traditional air source heat pump energy consumption waste mainly has the following three points:
fixed water level, single water replenishment method: a large number of air source heat pump units use temperature switches for water replenishment, and when set to a single temperature value, water replenishment is turned on. This kind of water replenishment method is too mechanical and cannot be mixed to replenish water. If it is changed, the circuit needs to be rebuilt. The inability to adjust the water level and water replenishment method in time as needed results in helpless energy waste.
lacks intelligent management and energy scheduling is not in place: a large number of air source heat pump units can only simply switch the temperature and time, and cannot flexibly respond to changes in weather and user water demand, and adjust themselves. As a result, excessive repeated heating and heat preservation are caused, and a large amount of electric energy is wasted. The deepening of the aging of the
unit will increase the energy consumption. As we all know, electronic equipment will change with the use of the equipment, thereby accelerating the aging degree, and then making the equipment energy consumption doubled. If the air source heat pump cannot perform the intelligent maintenance of the unit parts in time, many units seem to be normal, but in fact they are abnormal. If this continues, the energy consumption of the equipment will continue to rise as it is used, resulting in a lot of waste of electricity.
It can be seen that the abnormal use of the air source heat pump will greatly reduce its energy saving rate, resulting in excessive power waste.
2. Energy-saving innovation and management innovation of the heat pump supervision platform
Hunan Qingchuang Silk Road Technology Co., Ltd. has successfully launched the intelligent integration · central hot water energy-saving butler system through three years of research and development and application of the heat pump energy supervision platform.

Take an apartment in a city in Shanghai as an example. The hotel has a total of 4 floors and 135 existing guest rooms, using air source heat pumps for 24-hour heating. In January 2019, the Smart Fusion·Central Hot Water Energy-saving Butler System was installed. So far, the equipment has a stable rate of 99% and the comprehensive energy-saving rate of the equipment is between 30% and 40%.
takes the three-month energy consumption data in the winter from October 1, 2019 to December 31, 2019 as an example.
October-December winter water consumption is: 4552-3224=1328 tons
According to the "Building Water Supply and Drainage Code Requirements" issued by the National Housing and Construction Commission, the average cold water temperature in East my country in winter is 15°C, and the hotel hot water requires heating temperature It is 55-60°C, and the heating intermediate value is 57.5°C. The power consumption ratio of the air source to the water pump of the hotel’s central hot water system is 9:1, and the ratio of the internal hot water heating to the internal circulation power consumption of the air source heat pump in winter is 8:2, and the original actual power consumption of 1328 tons of water can be obtained. The amount of electricity is 45574 degrees.
Original electricity consumption = 1.25*V*C*ΔT÷0.9 (q*cop)
=1.25*1328000*1*42.5÷0.9 (860*2)=45574 degrees
The original electricity consumption in winter from October to December is: 45574 degrees
after October-December winter energy consumption: 25565 degrees
winter energy saving rate: through the intelligent energy-saving control box in winter from October to December, the hotel’s actual electricity consumption after three months of energy saving is 25565 degrees, the original electricity consumption It is 45574 kWh of electricity. A total of 20,009 degrees of energy saved in three months, and the amount of electricity saved is about 18,000 yuan. Energy saving rate in winter: 46%.
According to the data in 2019, the original electricity consumption of the air source heat pump in this city apartment in 2019 is about 138,855 kilowatt-hours of electricity, and the energy consumption of the central hot water energy-saving housekeeper is 92,478 kilowatt-hours after using smart integration.
