Problems solved by technology

[0004](2) Heat pumps often only consider the heating process, and the auxiliary cooling capacity is not easy to collect and utilize
[0005](3) If the existing single-stage refrigeration or heating equipment is to achieve deep cooling or heating, its energy efficiency ratio will inevitably decrease
[0006](4) At present, the technology of recovering waste heat from air conditioners to directly heat cold water has appeared on the market, but its recovery efficiency is low and energy cannot be fully utilized
[0011] To the best of the Applicant's knowledge, no such device or system is currently on the market

Embodiment 1

[0059] Embodiment 1: A cooling and heating system with a single compression circuit and a complementary circuit for cold and heat sources. See figure 1 .

[0060] In a refrigeration and heating system with a single compression circuit and complementary circuits for cold and heat sources, the heating subsystem is composed of a compression circuit, and the refrigeration subsystem is composed of a compression circuit.

[0061] The heating subsystem 10 , the cooling subsystem 20 and the circulation pump 22 are started synchronously through the system controller 30 .

[0062] The working principle of the heating subsystem 10 is:

[0063] The heating subsystem compressor 1 pressurizes the gaseous heating agent and sends it to the heating subsystem condenser 2 . The heating agent becomes liquid in the cooling coil 3 of the heating subsystem and releases heat. The medium-heat fluid enters the condenser 2 of the heating subsystem from the medium-heat fluid inlet 5 , is heated by t...

[0077] figure 2 It is a principle flowchart of the refrigeration and heating system with dual compression circuits and complementary circuits of cold and heat sources. repeat. The difference is: the heating subsystem has two compression circuits, which have greater power and stronger heating capacity than the single compression circuit; the cooling subsystem has two compression circuits, which have larger capacity than the single compression circuit. Power and stronger cooling capacity. The temperature difference between the cryogenic fluid and the high heat fluid in the whole system increases. The sub-controller of the heating subsystem regulates the working conditions of its own two compression circuits; the sub-controller of the refrigeration subsystem regulates the working conditions of its own two compression circui...

Embodiment 3

[0078] Embodiment 3: Refrigeration and heating system with four compression circuits and complementary circuits of cold and heat sources. See image 3 .

[0079] image 3 It is a flow chart of the principle of the refrigeration and heating system with four compression circuits and complementary circuits of cold and heat sources. repeat. The difference is: the heating subsystem has four compression circuits, which have greater power and stronger heating capacity than the double compression circuit; the refrigeration subsystem has four compression circuits, which have larger capacity than the double compression circuit Power and stronger cooling capacity. The temperature difference between the cryogenic fluid and the high heat fluid in the whole system increases. The sub-controller of the heating subsystem regulates the working conditions of its own four compression circuits; the sub-controller of the refrigeration subsystem regulates all the working conditions of its own f...
