Waste heat recovery energy-saving cold and heat source system

Abstract

The invention relates to a waste heat recovery energy-saving cold and heat source system. A cold and heat recycling heat pump unit is respectively connected with a tail-end air-conditioner water circulating system, a stainless steel heating heat-insulation water tank and a stainless steel storage heat-insulation water tank via pipes respectively, an output end of the tail-end air-conditioner waster circulating system is connected with an input end of the cold and heat recycling heat pump unit via a refrigerating water circulating pump pipe, an input end of the stainless steel heating heat-insulation water tank is connected with running water, an output end of the stainless steel heating heat-insulation water tank is connected with an input end of the stainless steel storage heat-insulation water tank, and the stainless steel storage heat-insulation water tank is connected with a household hot water supply system. The waste heat recovery energy-saving cold and heat source system has the advantages that as a traditional refrigerating system and a traditional heating system are combined into the waste heat recycling energy-saving cold and heat source system, energy consumption and running cost are reduced effectively, occupied area is saved, and the problems of noise, high temperature and the like which affect physical and psychological health of staff are solved. Besides, the system is high in automation degree, saves labor, can save energy by more than 40% averagely and does not pollute the atmosphere and the environment.

Description

[technical field] [0001] The invention relates to the technical field of cold and heat source systems, in particular to a waste heat recovery and energy-saving cold and heat source system. [Background technique] [0002] At present, most enterprises and institutions that use central air-conditioning and domestic hot water in hotels, hotels, hospitals, schools, bathing centers and swimming pools mostly use traditional cold and heat source systems, including two systems of cooling and heating. Cooling-only central air-conditioning and cooling towers are used to produce cold air, and boilers are used to produce heating and domestic hot water. The energy consumption of central air-conditioning and boilers is the largest energy consumer in building energy consumption, and with the price increase of oil, gas, coal, etc. The annual increase has brought more and more prominent impact on the energy consumption of users. A large amount of exhaust gas and waste heat from boilers has c...

AI Technical Summary

Problems solved by technology

A large amount of boiler exhaust gas and waste heat have caused serious environmental pollution, which has gradually intensified the urban heat island effect.

In addition, central air-conditioning and boilers are low in automation and need special personnel to take care of them, which wastes human resources; boilers occupy a large area, are noisy, and there are inevitably potential safety hazards due to the existence of fuel delivery pipelines
