Problems solved by technology

The cold storage density of the air conditioner is higher than that of the water cold storage system when storing and supplying cold; when storing and supplying heat, it solves the shortcomings of the existing heat pump air conditioner such as frequent defrosting and poor heating effect; When the temperature is lower than -10°C, the air conditioner can still supply heat to the room normally, and the heating temperature is uniform
An auxiliary electric heater 16 may be provided in the energy storage tank 13

Abstract

Disclosed is a air patenting heat hump energy storage air conditioner, comprising outdoor component, indoor component and energy storage device. The outdoor component includes compressor 1, cryogen pump 2, outdoor heat exchanger 3, throttle valve 4-5, four-way reversing valve 6 and solenoid valve 7-10; the indoor component includes indoor heat exchanger 11 and throttle valve 12; the energy storage device includes energy storage slot,13 energy storage coil pipe 14 and energy storage material 15. The invention has the advantages that it can reduce hill and increase dale and balance electric load, energy storage air conditioner is an effective method of electric load which needs reduction of hill and increase of dale, saves electricity cost and reduces machine volume, enlarges its use area, solves the problems of frequent defrostation in the present heat pump air conditioner and bad heating effect, and can operate normally under -10deg.C.

Description

1. Technical field [0001] The invention relates to an air conditioner, in particular to an air-cooled heat pump energy storage air conditioner. 2. Background technology [0002] Since the reform and opening up, my country's comprehensive national strength and people's living standards have been greatly improved. As one of the basic industries of the national economy, the electric power industry has achieved considerable development. However, the growth of electric power still cannot satisfy the rapid development of the national economy and the rapid growth of people's daily electricity consumption. The power shortage situation in the whole country still exists and is becoming more and more serious. At present, the power supply shortage is mainly manifested in the following aspects: 1. The load rate of the power grid is low, the peak-to-valley difference of the system increases, and the peak power is seriously insufficient, resulting in frequent power cuts in the power grid....
