Example Embodiment

[0086] A performance test method for a multi-energy complementary heating system applied to renewable energy-gas co-supply is carried out in the following steps:

[0087] 1. According to the connection mode and operation mode of each heating unit, set temperature, pressure and flow test points, and realize real-time collection;

[0088] 2. Determine the operating mode and time of each heating unit according to its own parameters, application environment, and water requirements of each heating unit, and select system performance test points and test parameters in this operating mode;

[0089] 3. Test the heat supply and total heat supply of each heating unit according to the following formula and calculation method, namely:

[0090] Q T =Q S +Q H +Q G

[0091] Q S = C m ×ρ m ×q 1 ×t 1 ×(T 2 -T 1 )

[0092] Q H =c×ρ×q 2 ×t 2 ×(T 4 -T 3 )

[0093] Q G =c×ρ×[q 3 ×t 3 ×(T 11 -T 12 )+q 4 ×t 4 ×(T 13 -T 14 )]

[0094] Where:

[0095] Q T --Total heat supply of the system, kJ;

[0096] Q S --The hea...

Abstract

A method for testing the performance of a renewable energy and gas powered multi-energy complementary heating system includes the following steps: (1) setting the temperature, pressure and flow test points according to the connection mode and operation mode of each heating unit, and collecting operation state parameters in real time; (2) determining the performance test points and test parametersof a multi-energy complementary heating system suitable for different heating unit combinations and operation modes; (3) putting forward a calculation method of the heating quantity of the system; (4)putting forward user heat gain test indexes and a calculation method; (5) testing the primary energy utilization rate of the system; and (6) calculating each test index of the multi-energy complementary heating system based on the calculation steps and methods. Three types of heating units, namely, a solar energy collector, an air source heat pump and a gas heating water heater, are integrated. The technical indexes and calculation methods used for performance test and effect evaluation are put forward and defined. The performance test and technical evaluation of a multi-energy complementaryheating system based on any combination are realized.

Description

technical field [0001] The invention relates to a testing method of a heating system, in particular to a performance testing method of a renewable energy-gas combined supply multi-energy complementary heating system and a testing device used therein. Background technique [0002] As the country pays more and more attention to the use of renewable energy, various forms of energy applications have emerged, and one of the very important trends is "from single energy to multi-energy complementarity". The multi-energy combination can not only achieve the purpose of energy saving and emission reduction, but also make up for the shortcomings of different energy sources. Through the rational allocation of energy sources, the green and comfortable quality of life of residents can be improved. In recent years, contradictions between heating demand and heating status, environmental protection and air pollution, fossil energy depletion and renewable energy stability have emerged in my c...
