Description
Technical Field
The utility model relates to a indirect heating equipment technical field especially relates to an air heat transfer device, liquid bag formula fin evaporator, air energy heat pump and water heater.
Background
Along with the increasing life and population growth of people, the consumed fossil energy is more and more, a large amount of greenhouse gas is emitted, the haze weather is frequent, particularly, the haze condition of the northern area in winter is much more than that of the weather in any historical period, the PM2.5 concentration is seriously out of standard, the method is not separated from the excessive dependence on the fossil energy by human, and the increase of population density is directly related to the excessive consumption of the fossil energy.
The environmental protection data show that the contribution rate of heat supply and industrial energy consumption fossil energy to the concentration of PM2.5 is about 61%. Among them, the most severe haze areas are caused by the phenomena of the fossil energy industry, such as the city, which is common in some cities in north China. Except Beijing and Tianjin, the proportion of the Beijing area in the fossil energy consumption structure is nearly 90 percent and far exceeds the average level of China.
Human beings excessively consume fossil energy and simultaneously discharge 30% waste heat of exhaust gas to the atmosphere, so that the greenhouse effect causes the ambient temperature of large area to rise, and the cold air stream group crosses the border and weakens, and tropical cyclone warm air stream group steam transportation is strong to last north.
As the consumption level of fossil energy in northern areas is higher than that in southern areas due to the development of heavy industry and the increase of population density in northern areas, suspended particles in the greenhouse effect of the fossil energy become the hydrometeor nuclei of warm and humid air flows, and therefore renewable energy sources with infinite energy are stored in areas with frequent haze.
However, this renewable energy source directly endangers human health. At present, the problem of frequent haze in the areas with dense population and developed industry in the world is solved, the haze treatment is basically a passive mode mainly based on capacity reduction, and the haze treatment research becomes the focus of global attention from the perspective of atmospheric ecological balance.
Therefore, the great development of the air energy heat pump air conditioner has very practical significance, which is about the great problems of sustainable development and human health, and is of great importance to ensure the quality of the ambient air.
However, the current air energy heat pump technology is not mature, especially in high humidity and low temperature environment, defrosting is a great problem, sometimes the defrosting lasts for almost the same time as the heating process, which seriously affects the user experience, and the energy consumption is huge, which is not much more advantageous than the boiler heating economy.
The problem of defrosting can be met if a closed heat source tower is adopted;
if an open heat source tower is adopted, the problem that the temperature of a solution freezing point moves upwards can be solved, once the open heat source tower moves upwards to a certain environment temperature node, a freezing pipe event is inevitably caused, the evaporator is inevitably scrapped, and the economic loss is huge.
At present, the technical scheme adopted by many enterprises is to continuously add concentrated antifreeze to prevent the freezing point temperature of the solution from rising, and the convenience is extremely unfriendly to the environment because the antifreeze can cause water and soil pollution.
The problem of defrosting is really a worldwide problem, and no defrosting method can achieve very accurate time effect (no delay and no excessive consumption are needed), is efficient, energy-saving and quick, and does not have a related defrosting technology.
The headaches of the existing defrosting technology are that heating is required to be stopped in the defrosting process, and heat is absorbed into a room for defrosting, which seriously influences the user experience, and the related technology of the existing defrosting is described.
At present, a more classical defrosting technical method adopts a fuzzy control theory, generally controls defrosting start and stop by sensing wind pressure transmission control information or room temperature change, and also adopts temperature difference-time control to start defrosting and temperature (or pressure) -time control to finish defrosting. It is also possible to control defrosting by using a humidity sensing element in combination with a time calculation method.
The factors are only time-reliable, and other factors are influenced too much by external change factors, so that accurate control is difficult to achieve.
Several air-cooled heat pump defrosting control methods are introduced here: this is achieved by measuring the evaporator outlet wind speed.
1. Firstly, carrying out simulation on a system to obtain the relation between the evaporation temperature and the air speed at the outlet of an evaporator;
2. calculating the evaporation temperature according to the wind speed measured by a wind speed sensor arranged at the outlet of the evaporator, obtaining the surface temperature of the evaporator according to the relation between the surface temperature of the evaporator and the evaporation temperature, and then determining whether defrosting is carried out according to the surface temperature of the evaporator;
3. and finally, determining whether defrosting is finished or not according to whether the air speed at the outlet of the evaporator reaches a threshold value in normal operation.
The defrosting control method of the air-cooled heat pump comprises the following steps:
1) carrying out simulation on the air-cooled heat pump, and establishing a simulation model of an outdoor unit, an indoor unit, a compressor and a throttling element;
2) according to the principles of pressure balance, mass balance and energy balance, the system is subjected to frosting operation simulation calculation, and the relation between the evaporator evaporation temperature and the evaporator outlet wind speed is obtained as follows:
3) an outlet of an outdoor unit evaporator is provided with a wind speed sensor; 4) setting the value of Δ tw and a threshold value of tw (e.g., Δ tw-1.5 ℃, tw-3 ℃), depending on the particular system; setting a time step length (such as 2min) and a wind speed threshold (such as 1.8m/s) in normal operation;
5) when the air-cooled heat pump starts to operate, substituting the wind speed measured by the wind speed sensor into a formula 1 within a time step to obtain an evaporation temperature t 0;
6) substituting the evaporation temperature t0 calculated by the formula 1 into a formula 2 to obtain the surface temperature tw of the evaporator;
7) judging whether the calculated surface temperature tw of the evaporator reaches a set value;
8) if tw reaches a set value, starting defrosting; 9 if not, continuing to operate;
9) after the defrosting is started, when the measured wind speed v reaches a set threshold value (for example, greater than 1.9m/s), the defrosting is finished, otherwise, the defrosting is continued. The defrosting control method is not only complicated, but also easy to judge by mistake and can not save energy.
The conventional defrosting method generally judges whether an evaporator is frosted through a temperature sensing bulb, and then carries out defrosting treatment. However, due to the reasons of uneven heat exchange, the heat exchanger cannot be thoroughly cleaned, and the heat exchanger is continuously deteriorated in the long-term operation process, which finally causes the evaporator to have an ice layer, which seriously affects the operation of the air conditioner, and the unreliable element is added. Therefore, the traditional defrosting treatment method has the defect of incomplete defrosting.
Therefore, there is a need to provide a new air heat exchanger to solve the above technical problems.
