Central air-conditioning cold and heat source supply system

Abstract

The invention discloses a cold and heat source supply system for central air-conditioning, which includes an air-conditioning terminal, a water chiller, a heat pump unit, a cooling device, an insulated water tank, and several circulation pipelines. The first drive device and the first switch device are set; the chiller is connected with the cooling device through the second circulation pipeline, and the second drive device and the second switch device are arranged on it; the chiller is connected with the heat preservation water tank through the third circulation pipeline, The third driving device and the third switching device are arranged on it; the heat pump unit is connected with the end of the air conditioner through the fourth circulation pipeline, and the fourth driving device and the fourth switching device are arranged on it; the heat pump unit is connected with the heat preservation water tank through the fifth circulation pipeline The fifth drive device and the fifth switch device are arranged on it; the cooling device communicates with the end of the air conditioner through the sixth circulation pipeline, and the sixth drive device and the sixth switch device are arranged on it. The system works efficiently.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a cold and heat source supply system for central air conditioning. Background technique [0002] With the improvement of people's demand for indoor environmental quality, air conditioners are also occupying an increasingly important position in people's lives and daily work, especially the construction of large public buildings (such as urban complexes, hospitals, etc.), making the central Air conditioners are widely used in cooling in summer and heating in winter, and sanitary hot water systems that occupy less heat demand in buildings have become an indispensable part of people's lives. However, central air conditioning systems and sanitary hot water systems in buildings have a certain To a certain extent, it is impossible to achieve a better complementary effect. The central air conditioner must dissipate heat into the air in summer cooling to produce cooling capacity to meet t...

[0002] With the improvement of people's demand for indoor environmental quality, air conditioners are also occupying an increasingly important position in people's lives and daily work, especially the construction of large public buildings (such as urban complexes, hospitals, etc.), making the central Air conditioners are widely used in cooling in summer and heating in winter, and sanitary hot water systems that occupy less heat demand in buildings have become an indispensable part of people's lives. However, central air conditioning systems and sanitary hot water systems in buildings have a certain To a certain extent, it is impossible to achieve a better complementary effect. The central air conditioner must dissipate heat into the air in summer cooling to produce cooling capacity to meet the cooling needs of the building. Although the domestic hot water system is installed in a certain To a certain extent, the use of non-renewable energy is avoided, but for the owner, the initial investment is increased, and the heat in the central air-conditioning system cannot be fully utilized, which is also an invisible waste of energy to a certain extent.
