Abstract

The invention discloses a cold and hot divided type multi-configuration dual heat source heating system with a heat pump. The cold and hot divided type multi-configuration dual heat source heating system comprises a heat demand side device and a supply side device, a first working medium runs in the cold and hot divided type multi-configuration dual heat source heating system, the supply side device comprises a first heat source, a second heat source, a heat storage water tank and a first circulation pump, the heat sources in the supply side device can supply heat to the heat demand side device through the first circulation pump, and heat is stored for the heat storage water tank through the first heat source and the second heat source; and the system further includes the heat pump, when the heat pump works, the supply side device and the heat demand side device are separated by the heat pump, and the supply side device supplies heat to the heat demand side device through the heat pump. The cold and hot divided type multi-configuration dual heat source heating system realizes organic fusion of the multiple heat sources, realizes organic fusion of the heat pump and the multiple heatsources, ensures stable and continuous heating, eliminates the conditions that as for the heat sources such as solar energy and wind energy in the past, excessive heating is caused if the collected heat is much and effective utilization cannot be achieved if the collected heat is less, improves the utilization rate of the heat sources on the supply side, improves the heat efficiency of the entiresystem, and improves the heating capacity of the system.

Description

technical field [0001] The invention relates to a cold and heat separated multi-configuration dual heat source heating system with a heat pump. Background technique [0002] In the prior art, energy with low price and expense is usually used as the energy source of the heat pump energy side (outdoor heat exchanger), including solar energy, geothermal energy (ground source heat pump), various water resource energy (ground water, surface water, sewage etc. - water source heat pump), and air energy (air source heat pump), etc. In order to obtain a higher proportion of clean energy heating applications and a more reasonable cost performance, dual-energy or multi-energy devices are often used in parallel to achieve multi-energy complementarity. However, due to the characteristics that heat sources from solar and / or wind energy can reach and exceed the design heating temperature, simple parallel connection limits the possibility of direct heating without heat pumps for such heat ...
