Overview
Product Name: Dual Head Water Source Heat Pump Product Overview: The water (ground) source heat pump system consists of four parts: the water (ground) source heat pump host (energy lifting equipment), the underground water well or buried pipe heat exchange system (energy extraction equipment), the end or ground heating system (energy release equipment), and the system piping accessories (energy transportation equipment). As shown in the figure below, in winter, the water (ground) source heat pump host transfers geothermal energy from groundwater or surface rock and soil to the indoor environment by consuming a small amount of electricity, achieving heating needs without the need for boilers and a large amount of electricity, saving energy and avoiding environmental pollution caused by smoke and dust. In summer, the water (ground) source heat pump host operates by cooling, transferring indoor heat to groundwater or surface rock and soil to achieve indoor cooling. System: Energy stable, energy-saving: The cold and heat sources are relatively stable and can operate. The screw functional efficiency ratio is as high as 6.0, the vortex functional efficiency ratio is as high as 5.0, and the comprehensive energy efficiency ratio is as high as 12.0; Green and Healthy Choice: Utilizing rivers/lakes as cold and heat sources for energy conversion, reducing the emissions of CO2 and other atmospheric pollutants. The unit can use R134a refrigerant; System advantages, one machine with multiple uses: integrating heating, air conditioning, and domestic hot water into one, enhancing economy; Flexible and versatile, easy to expand: There are various options for unit selection, which can simultaneously provide air conditioning and heating, achieving a four control effect. Reference to standard or specification: "Design Standard for Energy Efficiency of Public Buildings" GB50189-2005, "Cooling of Air Conditioning and Heating
Product Details

a.Gas fired boiler

Its thermal efficiency (referring to the percentage of the heat generated when the fuel fed into the boiler is completely used to produce steam or heat water or other working fluids) is generally65-85%Between them, take the middle value70%The calorific value of hot air is generally taken as37620kJ/Nm3.To obtain100kWThe amount of natural gas that needs to be input per hour is:(100 × 3600) ÷ (37620 × 0.7)=13.67 Nm3, if calculated based on the average price of natural gas2.10element/Nm3 calculations, the hourly natural gas cost is28.71Yuan, running on a daily basis8Calculated on an hourly basis, the daily operating cost of the unit is calculated229.68Yuan.

b.Air source heat pump unit

Its heating efficiency is generally in the range of3.2-4.0Between them, take the middle value3.6To obtain100kWThe heat requires input of electrical energy100 ÷ 3.6=27.78KW, which means an hourly electricity consumption of 27.78Kw · h. If calculated based on the average industrial electricity price of 0.75 yuan/kW in major regions, the hourly electricity cost is 20.84 yuan. If calculated based on 8 hours of operation per day, the daily electricity cost for unit operation is 166.68 yuan.

c. Water (ground) source heat pump unit

The heating efficiency ratio is generally between 4.5-5.0, with a median value of 4.75. To obtain 100 kW of heat, it is necessary to input electrical energy of 100 ÷ 4.75=21.05 kW, with an hourly electricity consumption of 21.05 kW • h. Calculated based on the average industrial electricity price of 0.75 yuan/kW • h in major regions, the hourly electricity cost is 15.78 yuan. Calculated based on 8 hours of operation per day, the daily electricity cost for unit operation is 126.24 yuan.
