On February 22, the 2021-2022 HC HVAC Industry Conference and the 16th Brand Event with the theme of "Gathering Industrial Strength to Create a Low-Carbon Future" were unveiled at the APEC National Leaders' Conference Center in Yanqi Lake, Beijing. The summit brought together thousands of HVAC elites, including industry experts and scholars, enterprise representatives, industry business representatives, professional media, etc., to conduct in-depth professional discussions on industry policy standards and planning, industry development situation, enterprise practice, supply chain construction, channel construction, technical solutions, cooperation and sharing, aiming to promote the HVAC industry to a higher level and work together to build a better life.
With the further deepening of the national "coal to electricity" and "double carbon" policies, many central heating projects in new and old communities have sprung up, and the market development has entered a new normal. At the same time, some design and construction difficulties of air source heat pumps in community central heating projects have also begun to be exposed, such as large footprint, high noise, difficult treatment of frost water, cold island effect and other problems have emerged one after another.
Cold island effect
What is the cold island effect? What are the consequences of the cold island effect? At the meeting, Chen Kui, senior engineer of Haiwu Group, answered the problem of cold island effect and noise of air source heat pump. The original meaning of the "cold island effect" corresponds to the concept of meteorological effects corresponding to the "heat island effect". In the field of air source heat pumps, the "cold island effect" refers to the fact that when the heat pump turns on the heating mode, the cold air around the heat exchanger continues to rise and sink, the surrounding temperature of the heat pump unit continues to fall, the temperature gradient of the entire temperature field continues to refine and expand to the surroundings, and the central temperature continues to decrease until a cold air layer is formed around the heat pump unit, resulting in a large temperature difference between the inside and outside the unit group (the temperature inside the air source heat pump group is 6°C~8°C lower than the outside temperature of the unit), so that the heating efficiency of the heat pump unit in the group is reduced. In order to avoid the cold island effect of the air source heat pump unit from the root, the unit must be reasonably arranged to ensure the ventilation of the unit.
Noise problems
Chen Kui, senior engineer of Haiwu Group, also discussed the noise problem of air source heat pump with the audience. Haiwu low ambient temperature air source heat pump (cold water) unit adopts advanced stepless frequency conversion energy-saving technology, standard equipped with remote DTU monitoring module, which not only realizes Haiwu's intelligent control and adjustment, can use mobile phone or computer login for real-time remote control, but also configures services, data analysis, alarm management and other functions, so that you can control the operation status at any time, so that the operation is more energy-saving and life is more comfortable. In addition to the advantages of the unit itself, the Haiwu team will also pay special attention to noise pollution during installation, and usually carry out comprehensive damping and sound insulation bandaging on the pipeline during installation, which can reduce the vibration of the pipeline on the one hand, and can play a role in isolating air sound on the other hand.
In order to commend a number of outstanding enterprises in the industry who are determined to forge ahead and innovate, further stimulate the new vitality of enterprise development, and promote the healthy and rapid development of the industry, the organizers also commended outstanding enterprises on the spot at the same time as the industry conference, witnessing the birth of the HVAC industry list with both strength and popularity.
Top 10 outstanding brands of air energy heat pumps
In the era of continuous change, Haiwu Group dares to break the waves and move forward, in the rapidly changing market, continuous innovation and continuous efforts! The organizer presented the "Top Ten Outstanding Brands of Air Energy Heat Pumps" award to Haiwu Group, and Wang Zhibi, director of Haiwu Qingneng Business Department, took the stage to receive the award as a representative. He said that winning this award is the industry's recognition of our brand and strength, and every bit of hard work will pay off! Good products will eventually be affirmed by all walks of life; A good brand will definitely be loved by the majority of consumers! Air energy heat pumps have entered thousands of households and various enterprises and institutions, and we are full of confidence in the future prospects of the air energy industry.
A trickle of water converges into the sea! As a well-known professional scenario digital energy and clean energy solution provider and its full life cycle management provider in China, Haiwu will lead the industry to provide more energy-saving, healthy and comfortable clean energy solutions for the society, and promote our country the HVAC industry to create a better future!
