With the acceleration of urbanization and people's increasing concern about environmental protection, traditional urban heating methods are facing severe challenges. The traditional heating mode represented by coal-fired boiler not only has the problem of pollution, but also causes the waste of energy. However, ultra-low temperature air source heat pump as a disruptive technology, is gradually changing the face of urban heating.

DR-ETP ultra-low temperature air source heat pump series is an energy regeneration device that uses air as a heat source for heat exchange. When the unit is heating, the refrigerant is used to absorb the heat of the air, and the absorbed heat and the input electric energy are released into the water through the reverse Carnot cycle, thereby producing high-temperature hot water. When the unit is refrigerated, the refrigerant is used to absorb the heat in the water, and the absorbed heat is released into the air through the reverse Carnot cycle, thereby producing low-temperature frozen water.

Ultra-low temperature air source heat pumps have many significant advantages. First of all, it does not need to burn fuel, which fundamentally solves the problem of environmental pollution caused by emissions such as furnace smoke and exhaust gas. Secondly, the ultra-low temperature air source heat pump can use energy efficiently by extracting the low temperature heat energy in the air and converting it into heat energy for heating. According to statistics, the energy efficiency ratio of ultra-low temperature air source heat pumps can usually reach 3-4, which is much higher than the energy efficiency ratio of traditional heating methods. This means that the use of ultra-low temperature air source heat pump heating can not only reduce energy consumption, but also reduce energy costs.

Moreover, DR-ETP ultra-low temperature air source heat pump series also has the following core designs. 1. It adopts jet enthalpy increasing technology and can operate stably in severe cold weather at -35 ℃ with wide operation range. 2. One machine has multiple functions and can be used for summer cooling, winter heating and domestic hot water. 3, high efficiency and energy saving, low operating cost, input 1KW electric energy can generate 4KW heat energy, the operating cost is about 1/3 of that of gas water heater and 1/4 of that of electric water heater, with remarkable energy saving effect. 4. Environmental protection, no pollution, no combustion and discharge, no damage to human body, and good social benefits.; 5, small footprint, modular combination, operation and maintenance.

The influence of ultra-low temperature air source heat pump in changing the way of urban heating is various. First, it can reduce dependence on traditional energy sources. Traditional heating methods mainly rely on limited energy resources such as coal and gas, while ultra-low temperature air source heat pumps use heat energy in the air and have better sustainability. Secondly, the smoke-free and noise-free characteristics of ultra-low temperature air source heat pumps can significantly improve urban air quality and the living environment of residents. Thirdly, the efficient energy utilization and the effect of reducing energy costs of ultra-low temperature air source heat pumps can provide residents with more affordable heating methods. In general, the promotion and application of ultra-low temperature air source heat pumps can achieve a comprehensive upgrade of urban heating methods and environment-friendly development.

The development of ultra-low temperature air source heat pump can not be separated from the support and advocacy. Policy support should be increased to guide market investment and R & D forces into the field of ultra-low temperature air source heat pumps. In addition, subsidies, tax cuts and other measures can be used to encourage enterprises and residents to choose ultra-low temperature air source heat pumps as a heating method. At the same time, it is necessary to formulate relevant standards and specifications to ensure the reliability and safety of the design, construction and operation of ultra-low temperature air source heat pumps.

Ultra-low temperature air source heat pump, as a subversive technology to change the way of urban heating, has great potential and advantages. With the continuous advancement of technology and the development of the market, it is believed that ultra-low temperature air source heat pumps will become the mainstream choice for urban heating in the future. By promoting the application of ultra-low temperature air source heat pump, we can upgrade the way of urban heating, improve the quality of life of residents, but also make an important contribution to environmental protection. Let us actively support and promote the development of ultra-low temperature air source heat pump technology, and jointly create a warm and sustainable urban future.
