All-in-one machine integrated with heat and cold sources

Abstract

The invention discloses an all-in-one machine integrated with heat and cold sources, comprising a compressor. The high-pressure outlet of the compressor is connected with a condenser of which the outlet is connected with the inlet of a throttle device; the outlet of the throttle device is connected with an evaporator; and the outlet of the evaporator is connected with the low-pressure inlet of the compressor. The all-in-one machine is characterized in that the condenser is formed by connecting a water-cooled condenser with an air-cooled condenser in parallel; the evaporator is formed by connecting a water-cooled evaporator with an air-cooled evaporator in parallel; one group of fluid flow passage of the water-cooled condenser is connected with the throttle device, while the other group of fluid flow passage of the water-cooled condenser is connected with a first circulating device; and one group of fluid flow passage of the water-cooled evaporator is connected with the low-pressure inlet of the compressor, while the other group of fluid flow passage of the water-cooled evaporator is connected with a second circulating device. The all-in-one machine can simultaneously supply heat and cold with less power consumption and little environmental pollution.

Description

technical field [0001] The invention relates to a cold and heat source integrated machine. Background technique [0002] The energy consumption of large buildings such as modern hospitals and hotels is characterized by large cooling and heat supply, and the supply medium of cold and heat sources is mainly chilled water and hot water (the water temperature is not high). The user side is scattered and there are two types of control requirements that differ greatly. [0003] The traditional cold source and heat source of existing buildings such as hospitals and hotels are separated, such as attached figure 1 As shown, on the one hand, the refrigeration unit emits considerable waste heat, and on the other hand, it uses a large amount of energy to burn steam. Although people have made every effort to improve the efficiency of refrigeration units and boilers and recover the waste heat, and have achieved certain results, they have not solved the fundamental problem of high energy...

AI Technical Summary

Problems solved by technology

Especially in summer, when the "energy booster" is converted to the main cooling, its efficiency (COP) is lower than that of the general single cooling unit. Also in winter, when the "energy booster" is converted to the main heating, when the temperature drops to To a certain extent, its efficiency is reduced to even lower than that of electric heating, and the waste of energy consumption in use is huge

[0006] From the above, it can be seen that the currently commonly used units cannot supply cooling and heating at the same time, and consume a lot of energy during use, and the pollution to the environment is also relatively large
