Problems solved by technology

[0004] (2) Heat pumps often only consider the heating process, and the by-product cooling 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] As far as the applicant is aware, there is no such device presently available on the market

Embodiment 1

[0059] Embodiment 1: A synchronous refrigeration and heating unit with complementary cold and heat sources in a single compression circuit. See figure 1 .

[0060] In a synchronous refrigeration and heating unit with complementary cold and heat sources in a single compression circuit, the heating end is composed of a compression circuit, and the cooling end is composed of a compression circuit.

[0061] The heating end and the cooling end are started synchronously through the unit controller 20 .

[0062] The working principle of the heating end is:

[0063] The compressor 1 at the heating end pressurizes the gaseous heating agent and sends it to the condenser 2 at the heating end. The heating agent becomes liquid in the cooling coil 3 at the heating end and releases heat. The medium-heated fluid enters the condenser 2 at the heating end from the medium-heated fluid inlet 5 at the heating end, is heated by the heat released by the heating agent to become a high-heated flui...

Embodiment 2

[0075] Embodiment 2: A synchronous refrigeration and heating unit with complementary cold and heat sources in dual compression circuits. See figure 2 .

[0076] figure 2 It is a principle flowchart of a synchronous refrigeration and heating unit with complementary cold and heat sources in dual compression circuits. Its refrigeration and heating working principles and temperature compensation control principles are exactly the same as those of synchronous refrigeration and heating units with complementary cold and heat sources in a single compression circuit. repeat. The difference is: there are two compression circuits at the heating end, which have greater power and stronger heating capacity than the single compression circuit; there are two compression circuits at the cooling end, which have greater power than the single compression circuit and greater cooling capacity. The temperature difference between the cryogenic fluid and the high heat fluid in the whole system i...

Embodiment 3

[0077] Embodiment 3: A synchronous refrigeration and heating unit with complementary cold and heat sources in four compression circuits. See image 3 .

[0078] image 3 It is a principle flowchart of a synchronous refrigeration and heating unit with complementary cold and heat sources in four compression circuits. repeat. The difference is: there are four compression circuits at the heating end, which have greater power and stronger heating capacity than the dual compression circuits; there are four compression circuits at the cooling end, which have greater power than the dual compression circuits and greater cooling capacity. The temperature difference between the cryogenic fluid and the high heat fluid in the whole system increases. The unit controller controls the working conditions of the four compression circuits at the heating end and the four compression circuits at the cooling end.

Abstract

The invention relates to a synchronous refrigerating-heating machine set with cold-hot source complement. A heating compressing loop evaporating coil and a refrigerating compressing loop condenser coil are arranged in a same shell pass, heat which is the by-product of a refrigerating compressing loop is supplied to a heating compressing loop and used as a heat source so as to realize the cold-hot source complement, thereby achieving the purpose that one end of the machine set generates pyrogenic liquid and the other end generates cryogenic liquid. As considering the possibility of unbalance of heat production of the condenser coil at the refrigerating end and the heat absorption of the evaporating coil at the evaporating end, a temperature compensator is arranged at the shell pass of a refrigerating-heating complementor so as to regulate and control the smooth and efficient running of the heating compressing loop and the refrigerating compressing loop, and the running of the compressing loops and the temperature compensator is controlled by a machine set controller.

Description

technical field [0001] The invention relates to a synchronous refrigeration and heating unit with complementary cold and heat sources. Specifically, the cooling capacity by-produced at the heating end is supplied to the cooling end as a cold source, and the heat by-produced at the cooling end is supplied to the heating end as a heat source, thereby A combined unit that realizes cold and hot complementarity. One end of this unit produces high-heat fluid, and the other end produces cryogenic fluid. Background technique [0002] With the development of science and technology and economy, air conditioners and heat pumps have become more and more widely used, and the technology has become more and more mature. However, there are still some problems in market applications, such as: [0003] (1) The air conditioner often only considers the refrigeration process, and the heat generated by the condenser must be equipped with a heat dissipation system to dissipate the heat. Especiall...
