Seawater source heat pump (sewage source heat pump)It is a heat pump unit that uses seawater as a water heat source to produce high-temperature hot water (the highest temperature of hot water can reach)100It is mainly used for land release in special geographical environments such as aquaculture farms with seawater sources (sewage sources), coastal islands, industrial wastewater, water treatment plants, etc.

Seawater contains abundant energy. Sea water source heat pump is a heat pump technology that uses the principle of heat pump to transfer low-level thermal energy in seawater to high-level thermal energy through a small amount of electrical energy input. At present, seawater source heat pumps have been widely used in many foreign countries, especially in Northern Europe where they have been applied on a large scale. China, as a country with a long coastline and large-scale marine aquaculture, is one of them. Seawater source heat pumps have also been applied to a certain extent.

Our company specializes in designing seawater source heat pumps specifically for corrosive types of seawater or wastewater sources, overcoming the high salt content and corrosiveness of seawater. The pumps mainly contain sodium chloride, magnesium chloride, and small amounts of sodium sulfate and calcium sulfate, which have strong corrosion and high hardness. Preventing seawater corrosion is crucial in the design process. The second consideration is microbial nourishment. In coastal areas, tidal movements often cause sediment to move and accumulate, especially in muddy beach areas. At the same time, marine attachments are very abundant, including seaweed, bacteria, and microorganisms. Under appropriate conditions, they multiply in large numbers and attach to water intake structures, pipelines, and equipment, which can easily cause blockages and pose a great threat to the reliable operation of the system. The design of water intake is crucial. The third challenge is tidal changes. Tides and waves, every12An orgasm occurs every hour,6A low tide occurs after an hour, causing a change in water level2-3About meters, waves are caused by wind and have great destructive power. The design of water intake structures should fully consider the effects of tides and waves.

Our company's sewage source heat pump has the characteristics of high energy efficiency, compact structure, beautiful appearance, easy operation, and simple refrigeration system process. The refrigeration and heating process is achieved through the switching of water system pipelines. At present, sewage source heat pump units have been widely used in shopping malls, hotels, guesthouses, hospitals, factories, office buildings, northern centralized heating, industrial heat recovery, seawater aquaculture, industrial high-temperature hot water and other occasions.

The seawater source heat pump (sewage source heat pump) mainly has the following characteristics:

1. Compact structure, smooth operation

unitThe condenser and dry evaporator both use high-efficiency heat transfer tubes, and the main engine adopts imported high-efficiency semi enclosed twin-screw compressors, which have many advantages such as compact structure, small volume, light weight, and small installation position. The semi closed twin-screw compressor has fewer moving parts, and the compressor adopts5：6Ultra efficient screw rotor, with no direct wear between rotors and high reliability. Due to the fact that screw machines are continuous compressors without pulsationSeawater source heat pump unitIt has the characteristics of stable performance, low noise, small vibration, and smooth operation. Improved efficiency compared to reciprocating compressors20%—30%, has been obtainedIS09001International quality certification and patents from multiple European and American countries;

2. A comprehensive energy control system

Sewage source heat pumpEquipped with a four level capacity control system, energy regulation:[100、75、50、25(or activated,0Automatically adjust the start and stop of the unit according to load changes, which is more energy-efficient;

3. Independent refrigeration cycle system

high-capacitysnailSeawater source heat pump unitHaving two or more independent refrigeration circuits, even if one circuit fails/Maintenance, the other circuit can also operate normally. Equipped with mutual backup function, especially suitable for use in air conditioning and industrial non-stop environments;

4. Easy and intuitive operation

The unit adopts a microcomputer programmable controller（PLCChinese or English display), touch screen display, select the operation according to the menu on the screen, and directly touch the display button on the screen with your finger to startWater (ground) source heat pump chiller unitThe screen can display the operating status of the unit at any time, and can display parameters in two ways: graphics and text tables, making it clear at a glance;

5. Protection function of microcomputer controller

Equipped with protection against high compressor coil temperature, timed oil preheating and power on/off, cold water flow switch, and protection against low cold water outlet temperatureY- △ Protection against startup failure, high exhaust temperature, compressor overload, power loss memory function, frequent start stop protection, abnormal voltage protection, low oil level protection, high and low voltage protection, and other protection functions;

6. High degree of automation control:

Fully functional and capable of achievingScrew water (ground) source heat pump unitStart stop program management, timed control, water pump management, full function fault alarm, and fault self diagnosis function. Simultaneously equippedRS485Communication interface, convenient for users to achieve centralized and remote monitoring of the unit;

7. Significant environmental benefits:

It is a heating and air conditioning system that utilizes surface water as a cold and heat source for energy conversion. Heating eliminates the need for boiler room systems such as coal, gas, and oil, eliminating the combustion process and avoiding pollution such as exhaust and discharge; When providing cooling, the cooling tower is omitted, avoiding the noise, mold pollution, and water consumption of the cooling tower;

8. energy conservation and environmental protection

The electricity used is a clean energy source, and a well-designed water source heat pump unit is equivalent to reducing the cost compared to air source heat pumps30%The above electricity consumption is equivalent to a reduction compared to electric heating70%The above electricity consumption. So, water source heat pumps not only save energy but also reduce and decrease the pollution emissions and greenhouse effect generated during the primary energy consumption process during power generation;

9. Easy to install

allSewage source heat pumpunitAll components have been installed and tested in the factory, and refrigerant and refrigeration oil have been added. Users only need to connect the water and circuit to put them into use, reducing installation and debugging time;

In short, our company's seawater source heat pump (sewage source heat pump) adopts a special material design, with a corrosion-resistant condenser, evaporator matched with an efficient refrigeration system and control system, which has high efficiency, stability and energy saving, and has won the favor and recommendation of customers.
