Abstract

The invention discloses an energy storage system capable of simultaneously supplying cold and heat. The energy storage system comprises a water chilling unit and a heat pump unit, the evaporator sideof the water chilling unit communicates with a first heat exchanger through a cold supply pipe for cooling, the condenser side of the heat pump unit communicates with a second heat exchanger through aheat supply pipe for heating, and a cold storage tank connected with the cold supply pipe in parallel and a heat storage tank connected with the heat supply pipe in parallel are further included. Theenergy storage system is provided with the cold storage tank and the heat storage tank, when the electricity price is at the low ebb at night, the cold storage tank and the heat storage tank can be used for energy storage, the cold capacity and the heat capacity of the cold storage tank and the heat storage tank can be released to be used by the first heat exchanger and the second heat exchangerto supply heat and cold to the user side when the electricity price is at the high peak state in daytime, peak shifting of the electricity is achieved, and the use cost is reduced.

Description

technical field [0001] The invention relates to the field of energy storage systems, in particular to an energy storage system capable of simultaneously supplying cooling and heating. Background technique [0002] In some usage scenarios, it is necessary to supply cooling and heating at the same time. Taking the low-temperature dryer as an example, the existing technology is to supply heat to the low-temperature dryer through the cooling capacity of the evaporator and the heat of the condenser in the heat pump unit. And cooling requires a large amount of electric energy. The national power system implements a peak-valley electricity price system, and the existing heat exchange system cannot store energy, and it cannot be adjusted according to the peak-valley electricity price to save costs. Contents of the invention [0003] In order to solve the technical problem that the combined cooling and heating system in the prior art cannot store energy, the present invention propo...
