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

[0064] Embodiment 1: A cooling and heating system with a single compression circuit and a cold and heat source complementer. See figure 1 .

[0065] In the controllable single-compression loop heating and cooling complementary refrigeration and heating system, the heating subsystem is composed of a compression circuit, and the refrigeration subsystem is composed of a compression circuit.

[0066] The heating subsystem 10 , the refrigeration subsystem 20 , the cooling circulation pump 22 and the heat removal circulation pump 24 are started synchronously by the system controller 40 .

[0067] The working principle of the heating subsystem 10 is:

[0068] 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 heat-fluid inlet 5 of ...

Embodiment 2

[0084] Embodiment 2: Refrigeration and heating system with dual compression circuits and cold and heat source complementers. See figure 2 .

[0085] figure 2It is a principle flowchart of the refrigeration and heating system with double compression circuit and cold and heat source complementarity. Its refrigeration and heating working principle and control principle are exactly the same as those of the refrigeration and heating system with controllable single compression circuit and cold and heat source complementarity. Here I won't go into details. 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. Th...

Embodiment 3

[0086] Embodiment 3: Refrigeration and heating system with four compression circuits and cold and heat source complementers. See image 3 .

[0087] image 3 It is a flow chart of the principle of the refrigeration and heating system with four compression circuits and cold and heat source complementarities. 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 four compression circui...

Abstract

The invention relates to a cooling and heating system with a cooling-heating source complementor, mainly comprising a heating subsystem, a cooling subsystem, the cooling-heating source complementor and a temperature compensator. The cooling-heating source complementor is connected in series between the heating subsystem and the cooling subsystem; a cooling circulating pipeline is arranged betweenthe cooling-heating source complementor and an evaporator of the cooling subsystem; and a heating circulating pipeline arranged between the cooling-heating source complementor and the cooling subsystem, therefore, the cooling source and the heating source complement each other. In addition, the temperature compensator is arranged on the cooling-heating source complementor and comprises an undercooling compensating bypass and an overheating compensating bypass. The cooling and heating system is adjusted and controlled by a controller thereof, thereby being capable of cooling and heating synchronously.

Description

technical field [0001] The invention relates to a refrigeration and heating system with a cold and heat source complementarity, which is mainly composed of four parts: a heating subsystem, a refrigeration subsystem, a cold and heat source complementarity and a temperature compensator. Specifically, a cold and heat source complement is connected in series between the heating subsystem and the refrigeration subsystem; a cooling and cooling cycle pipeline is set between the cold and heat source complement and the heating subsystem evaporator, and the cold and heat source complement A heat rejection circulation pipeline is set between the condenser of the refrigeration subsystem to realize cold and heat complementation; a temperature compensator is set on the cold and heat source complement, including a subcooling compensation bypass and an overheating compensation bypass. The whole system is regulated by the system controller, and the heating is realized synchronously while cooli...
