First, the heat pump triple for the solution

 

1、System schematic:

  

 

2、Operating principle:

1) collector: air source heat pump unit running, from the outdoor low temperature air to absorb heat.

2) Heating: When the indoor temperature is lower than the set value, the system will run the heat of heat absorption to the water, while the circulating pump to run, the heat transfer to the indoor heating.

3) Refrigeration: summer test room temperature is higher than the set value, the unit running from the indoor heat absorption, reduce the indoor temperature

4) antifreeze: pipe and water tank to increase insulation, prevent the system freeze.

5) hot water: heat pump unit running, from indoor (summer) or outdoor (winter) to absorb heat, circulating pump operation, the heat transfer to the tank, the supply of hot water.

3, the scope of application:

  Sports venues and so on

4、System Features:

1) air source central air conditioning, hot water unit, can be flexible matching, partition control, to meet the different functional areas of the heating and cooling temperature and hot water demand.

2) unit installation is convenient, low operating noise.

3) unattended, intelligent operation, to meet the cold and warm demand, while providing adequate hot water, so that the environment more comfortable.

5, energy saving effect:

For example: a sports venues area of 1500m2, height 10m.

Design: air source heat pump heating / cooling.

Annual savings cost: 264,000 yuan

Equivalent to saving standard coal 79t / year, CO2 reduction 221t / year

 

Second, solar energy hot water solutions

Energy conservation

1. collector area: 160m2;
2. Electricity consumption: 6.2 * 104kwh / year
3. Solar energy savings: 19.7t / year
4. Carbon dioxide emission reduction: 53.2t / year

1. collector area: 160m2;
2. Electricity consumption: 4.2 * 104kwh / year
3. Solar energy savings: 26.7t / year
4. Carbon dioxide emission reduction: 72.1t / year

Note:
1. To compare the use of 10T / day hot water as an example;
2. To light the general area of rain and snow weather for 100 days to compare.
3. Cold water temperature: 10 ℃, hot water temperature: 60 ℃.
