Can 5 air heat pump heating cost cheap
In Chengdu and the surrounding area, my experience is that the use of 5 air energy heat pump heating is cheaper, its energy consumption can be calculated for reference, detailed as follows:
What is the total heating area that these types of machines and equipment can meet?
Air energy heat pump water heater from the manufacturer's technical manual, can directly know in the winter outdoor natural environment temperature (dry bulb temperature) 6 degrees, when the temperature of the water 45 degrees, 5 air energy heat pump rated heating capacity is 16KW, its rated power consumption is about 5KW, in other words, 5 degrees per hour power consumption, can obtain 16KW heating capacity. The rated gas consumption of 16KW natural gas wall hanging furnace is 1.9m³/ h, which can also be known from the manufacturer's technical manual.
In Chengdu, the heat consumption of each square meter in the room is calculated by 120 watts/square meter -140 watts/square meter. Therefore, the heat consumption of each area in the room is calculated according to the different heat insulation and insulation performance of the house structure. The sum of the obtained heat output is divided by 16KW. Therefore, 16KW heat can meet the total heating area of about 120-140 square meters.
How does their energy use compare in winter heating?
In Chengdu in winter, it is common for the average outdoor temperature to be 2-8 degrees Celsius, and the temperature in the room is set at 18-20 degrees Celsius. The average daily overload operation is 8-10 hours:
1. Air energy heat pump server, rated power consumption output power is 5KW, residential electricity price is estimated at about 0.6 yuan/KWH, that is, 5×10 hours ×0.6 yuan ×30 days =900 yuan/month;
2. 16KW calorific gas water heater, rated gas consumption is 1.9 cubic meters/hour, household gas gas price is estimated at 2.5 yuan /m³, that is, 1.9×10 hours ×2.5 yuan ×30 days =1425 yuan/month.
Note: in Chengdu, this type of household area using natural gas wall hanging furnace, often do not apply 16KW model, because its domestic hot water flow is very small, can not meet the number of households and vertical middle population application of boiling water (unless it is only 2-3 people), but should be applied 24KW model gas water heater, so that it in the winter after heating gas consumption is: 2.8 x 8 hours (it has a large amount of heat, so the use of time will be short) x 2.5 yuan x 30 days = about 1700 yuan/month, this is the real heating area in 120㎡ when the actual gas consumption.
Here are in the case of ground heating is compared, because the power supply temperature of the air heat pump can reach the maximum of 55-58 degrees (the actual brand power supply temperature difference), it is in line with the characteristics of the ultra-low temperature radiation source heating, and the natural gas wall hanging furnace is able to heating the ground heating and heating sheets, it is also their fundamental difference.
summary
In the background of increasingly poor natural gas resources, the provision of green environmental protection, the use of electromagnetic energy to promote heating is the contemporary trend, 5 air energy heat pump in Chengdu and the surrounding application, not easy to be independent just for heating, will continue to be used for central air conditioning cooling, that advantage can reflect incisively and vividly.
At present, because of the difference of well-known brands and function performance on the market, there is a big difference in the price of the host, the price is too low the result of the server is the operation noise, low water temperature caused by high energy consumption, and then high failure rate, this is we should pay attention to when using, can not be too pursuit of perfect cheap and ignore the quality.
