Seawater source heat pump technology enters coastal cities

What kind of energy is inexhaustible and clean? According to this article, the cleanest energy source should be nuclear fusion. The raw material for nuclear fusion is helium, which can be extracted from seawater. A plutonium extracted from one litre of seawater can release 300 litres of gasoline. The total amount of water in Shanghai's Earth is very large. Therefore, the total reserve of plutonium can be estimated to meet the energy needs of humans from 5 million to 100 billion years. This is inexhaustible for human beings and is inexhaustible. The energy crisis has already begun to invade the world. The earth’s oil, coal, etc. will be exhausted within a century. Scientists believe that the extraction of helium from seawater makes it react with helium at a high temperature of 100 million degrees Celsius. The helium extracted from 1 liter of seawater releases the energy in a complete fusion reaction and is equivalent to burning 300 liters of gasoline. Heat energy.

In this way, the energy of the seawater source is a high-tech topic, and it seems that there is still a great span from the use of seawater sources to the homes of the people. Is there a new way to use seawater sources to solve people’s problems in real life, such as heating and cooling?

For example, when people enjoy warmth, issues such as “how much coal will be burned for heating” in the heating department and “how much dust will be emitted to the atmosphere by the heating department” cannot be avoided. When people want to enjoy the cool and comfortable, how much electricity the electric power department has to send and how much coal it burns, how much dust the environmental protection department emits to the atmosphere is repeating itself.

PM2.5 has become a hot word and is not unrelated to people's traditional lifestyle. The US Air Quality Index AQ1 is only calculated from the PM2.5 concentration value. In addition to monitoring PM2.5, the Beijing Environmental Protection Center also monitors PM10, SO2, NO2, and CO. Ozone (O3) The five pollutants, and calculate the air quality index IAQI of each pollutant, and take the maximum value of each subindex as the value of the current air quality index AQI. In the past decade, people's production and business activities have come at the expense of the environment. New energy has become a topic of increasing concern to people. Seawater source heat pump technology is produced in such an environment.

There are inexhaustible sources of energy in seawater, and the development and utilization of seawater sources have caused scientific concern. What is the principle of seawater heat pump technology?

The seawater-source heat pump technology is a low-temperature, low-level thermal energy resource formed by using solar energy and geothermal energy absorbed by the shallow water source (seawater) on the earth's surface, and adopts the principle of heat pump to realize the transfer of low thermal energy to high thermal energy through a small amount of high-level electric energy input. technology.

Seawater absorbs the considerable radiation energy that the sun enters into the earth, and the temperature of seawater is generally quite stable. The working principle of a seawater source heat pump unit is to use seawater as the basic “source” for extracting and storing energy. It uses the refrigeration compression system to consume a small amount of electric energy and “takes out” the low-grade energy stored in seawater in winter to give buildings. Heating; In the summer, the energy in the building is “taken” out and released into the sea water to achieve the purpose of adjusting the indoor temperature. The greatest advantage of this unit lies in its efficient use of resources. First, although it uses seawater as the “source,” it does not consume seawater nor pollute the seawater; secondly, it has high thermal efficiency and consumes 1 kilowatt of electric energy, and it can obtain 3 The amount of heat or cooling from kW to 4 kW fundamentally changes the traditional way of energy use.

The seawater source heat pump has been receiving attention from coastal cities and has a broad application prospect. However, there are still some problems in the seawater source heat pump system, and many related experts and companies are required to solve it together.
