Factory Supply Water Chiller Industrial - Water-Ground-Lake Heat Pump Unit – Sunvi Detail:

Application :

Ground water source heat pump can be widely used in central heating and refrigeration in hotels, office buildings, schools, shopping malls, villas and residential areas, as well as air conditioning in other commercial and industrial buildings. It can also be used in swimming pools, bathing centers, beer brewing, cold rolling forging, cold storage and indoor planting and constant temperature breeding industries. A multi-purpose machine can provide cooling, heating and domestic hot water by using a set of equipment. For air-conditioning system, a heat pump provides two kinds of heat sources, which can save one-time investment. Its total investment is only 60% of the traditional air-conditioning system. It is easy to install, less installation workload than other air-conditioning systems, shorter installation period and easier to change installation. Compared with conventional air conditioning technology, water source heat pump has the following advantages:

1. High efficiency and energy saving
Ground water source heat pump (GSHP) is the most energy efficiency ratio (COP) refrigeration and heating mode in air conditioning system at present. The theoretical calculation can reach 7, and the actual operation is 4-6. Water-source heat pump consumes 1 kW.h of power, and users can get 4.3-5.0 kW.h of heat or 5.4-6.2 kW.h of cooling. Compared with air source heat pump, its operation efficiency is 20-60% higher, and its operation cost is only 40-60% of that of common central air conditioning.
2. Renewable Energy Utilization Technology
Ground Water Source Heat Pump (GSHP) is a heating and air-conditioning system that uses solar energy resources stored in the earth’s water body as a cold and heat source for energy conversion. The available water bodies include groundwater or rivers, part of the surface rivers, lakes and oceans. Surface water is used as cold and heat source, which emits heat or absorbs heat, does not consume water resources, and does not cause pollution to it. Boiler room and auxiliary coal yard, oil storage room, cooling tower and other facilities are omitted. The area of machine room is much smaller than that of conventional air conditioning system, saving building space, and conducive to the beauty of the building. This makes it possible to utilize nearly unlimited solar energy or land stored in it. Therefore, the water source heat pump is a clean and renewable energy technology, with significant environmental benefits.
3. Stable and reliable operation and convenient maintenance
The temperature of water body is relatively stable throughout the year, its fluctuation range is far less than that of air, and the temperature of water body is relatively constant, which makes the heat pump unit run more reliable and stable, and also ensures the efficiency and economy of the system. It adopts full computer control and has a high degree of automation. Because the system is simple, the unit components are few and the operation is stable, the maintenance cost is low and the service life is long.
After-sales service is solemnly committed to the principle of improving customer satisfaction:
1. The company establishes complete data files for the products sold, and has a professional and capable after-sales team to provide all-round tracking service and excellent after-sales service.
2. According to the actual needs of users to provide a complete use and design plan from equipment selection to site design, engineering installation, after-sales service as a whole.
3. At any time to solve the task technical problems for you, the company will regularly visit the status of equipment use; after-sales service team will periodically inspect, prevent trouble before it happens, so that you truly experience excellent service quality.
4. Carry out timely after-sales maintenance and maintenance services in strict accordance with the after-sales service terms. The free warranty period is one year, and the maintenance of spare parts is provided free of charge during the warranty period.
5. Lifelong maintenance, equipment failure after the expiration of the warranty period, damaged parts are only charged at factory price.
