How to get from Wendeng to Weihai New Wharf

Water source heat pump is a high-speed air conditioning system efficient and energy efficient that uses shallow underground geothermal resources (also called geothermal energy, including groundwater, soil or surface water, etc.) that can provide both heating and cooling. Water heat pumps achieve the transfer of thermal energy from low temperature locations to high temperature locations by injecting a small amount of high quality energy (such as electrical energy). Energy from the ground is used as a heat source for heat pump heating in hiver and as a cold source for air conditioning in summer. That is, in winter, heat from the ground's energy is "extracted" and the temperature is raised to provide indoor heating. ; in summer, internal heat is removed and released. Enter the energy of the earth. Typically, water heat pumps consume 1 kW of energy and users can get more than 4 kW of heat or cooling.

According to the heat source fluid of the heat pump, heat pumps can be divided into air heat pumps and water heat pumps, and water heat pumps are divided into water ring heat pumps and geothermal pumps. heat pumps. Water ring heat pump is a heat pump that makes full use of indoor waste heat. In winter, when the indoor waste heat is insufficient, it can be used for. Boilers are used for heating; in andHowever, when there is too much heat lost internally, cooling towers can be used to remove the heat. The application of geothermal heat pumps has just started in China. There are many terms related to geothermal heat pumps and they are not standardized. To avoid confusion, the standard terminology specified by ASHRAE in 1997 is now uniformly used, namely soil. geothermal heat pump (Ground-Source Heat Pump, GSHP). Geothermal heat pump is a general term that includes heat pump systems that use groundwater, surface water, and soil as heat sources and sinks. A heat pump system that uses the ground as a heat source and heat sink is called a ground-coupled heat pump (GCHP); a heat pump system that uses groundwater as a heat source and heat sink is called a heat pump on eunderground (GWHP). ). ); A heat pump system that uses surface water as a heat source and heat sink is called a surface water heat pump (SWHP).

Working principle

As a natural phenomenon, heat always flows from the high temperature end to the low temperature end. But just like a water pump raises water from low to high temperatures, people can use heat pump technology to pump heat from the low temperature end to the high temperature end. Therefore, the heat pump is essentially a heat production device. It consumes part of the energy itself, exploits the energy stored in the environmental medium and increases the temperature for its use. The work consumed by the entire heat pump device is only one. third of the heat supplied. One or less is the key to energy savingsheat pumps. The working principle of the water heat pump unit is to utilize the low-level thermal energy resources formed by shallow geothermal energy on the earth's surface, such as soil, groundwater or surface waters (rivers, rivers, seas, lakes or shallow pools). ). Through a small amount of high-level electrical energy, the evaporation of the refrigerant is used to remove heat in the air-conditioned space in summer and release heat into the closed circulating water, because the source temperature water is high. low, heat can be discharged effectively; in winter, the evaporation of the refrigerant is used to absorb heat. The heat of the water in the closed circulation is increased by air or water as refrigerant, then the heat is released in the condenser to the conditioned space.

The heating and air conditioning system by heat pumpWater is mainly divided into three parts: outdoor geoground energy heat exchange system, water source heat pump unit and indoor heating and air conditioning terminal system. There are two main types of water heat pumps: water-to-water type or water-to-air type. The heat transfer between the three systems relies on the heat transfer fluid water or air. The heat transfer fluid between the water heat pump and the underground energy is water, and the heat transfer fluid with the building heating and air conditioning terminal can be water or. air

Advantages and disadvantages

The water heat pump air conditioning system mainly has the following technical advantages:

(1) The water heat pump water uses solar energy resources stored in Earth's bodies of water as a source of cold and heat to perform energy conversion for heating and air conditioning systemsion. Water bodies that may be used include groundwater or rivers, surface rivers and lakes, and oceans. Soil and surface water not only act as giant solar collectors, collecting 47% of sunlight. The energy from the radiation is more than 500 times greater than the energy used by humans each year (the groundwater bodies receive energy from solar radiation indirectly through the ground), and it is a huge dynamic energy balance system. The soil and water bodies on the surface naturally maintain energy reception. and divergence. This makes it possible to exploit the almost unlimited amount of solar or geothermal energy stored there. Therefore, the water heat pump is a technology that uses clean and renewable energy.

2) The water temperature available for the water heat pump unit is 12-22°C in winter. The temperaturere of the water is higher than the ambient air temperature, so the evaporation temperature of the heat pump cycle increases. and the energy efficiency rate also increases. In summer, the water temperature is 18-35°C, and the water temperature is lower than the ambient air temperature, so the condensing temperature of refrigeration is reduced, making the cooling effect better than air-cooled and cooling tower types, and the efficiency of the unit is improved. According to estimates from the U.S. Environmental Protection Agency (EPA), a well-designed and installed water source heat pump can save users an average of 30 to 40 percent on heating operating costs, air conditioning and air conditioning.

(3) The temperature of the water body is relatively stable throughout the year, and its fluctuation range is much smaller than the fluctuation ofe the air. It is a good heat source for heat pumps and cold sources for air conditioners. The relatively constant temperature of the water body makes the operation of the heat pump more reliable and stable, and also ensures the efficiency and economy of the system. There are no difficult problems such as winter defrosting of air source heat pumps.

(4) Water source heat pumps use electrical energy, which is a source of clean energy. However, when they produce electricity, they consume primary energy and. causes emissions of pollutants and greenhouse gases CO2. Therefore, energy-efficient equipment itself causes less pollution. The electricity consumption of a well-designed water heat pump equates to a reduction of more than 30% compared to an air source heat pump and equates to a reduction of more than 70% compared to electric heating.

Of course, like anything, water source heat pumps are not perfect and their applications will also be limited.

(1) Subject to conditions of available water source. In theory, water heat pumps can use all water resources. In fact, in real projects, the cost difference in using different water resources is quite large. Therefore, whether there are suitable water sources in different areas has become a key to the application of water heat pumps. Among current methods of using water heat pumps, closed systems generally have higher costs. In open systems, the ability to find a suitable water source becomes a limitation for the use of water source heat pumps. For split systems, water source requirements must meet certain temperatures, water volumes and cleanliness.

(2) Limited by the geographical structure of the water layer. For the use of groundwater pumping for recharge, the geological structure of the place of use should be taken into consideration to ensure that a suitable water source can be found by drilling a well under economical conditions at the same time, the local geology. and soil conditions should also be considered to ensure that the waste water after use can be recharged.

(3) Limited by the economics of investment. Due to the influence of different regions, different users, national energy policies and fuel prices, the basic conditions for one-time investment and operation of water sources are different; Fees vary depending on the user. Although generally speaking, water heat pumps have higher operating efficiency and lower costs. CepeHowever, compared with traditional air conditioning, cooling and heating methods, the investment costs of water heat pumps will be different according to the conditions of different needs in different regions.
