Air source heat pump cold and hot double-storage air conditioning device

Abstract

The invention relates to an air source heat pump cold and hot double-storage air conditioning device. The device comprises two parts of a heat pump type air conditioner outdoor device and a heat pumptype air conditioner indoor device, wherein the heat pump type air conditioner indoor device comprises a shell hollowed and opened at the two ends, a base fixedly connected to the bottom of the shelland communicating with the external, an electric heating device arranged in a water tank, a refrigerant-water heat exchanger arranged in the water tank and used for heating or cooling water, and a fanmounted under the water tank; an air way for enabling air currents to pass through is formed between the shell and the water tank; an air cap is arranged at the end, far from the base, of the shell;and air outlets are formed around the air cap. The device has the advantages of capability of realizing room-stage cold and hot storage, simple structure, low mounting cost and high safety and reliability, and provides excellent solutions for such important demands as cleaning and warming in cold regions, power grid load balance, heating and cooling operation cost reduction and cleaning energy consumption.

Description

technical field [0001] The invention relates to the technical field of heating and air-conditioning equipment, in particular to an air-source heat pump cooling and heating dual-storage air-conditioning device. Background technique [0002] At present, the country is vigorously promoting "clean heating" technology. With the improvement of the environment and the increasing requirements for eliminating smog, reduce or prohibit the use of non-renewable resources such as coal, gas, and oil for heating or environmental protection. Clean heating is the current and future heating policy for polluting heating methods. Among them, the use of electric heating instead of coal-fired heating is a technical measure vigorously promoted by the government. According to the current implementation of electric heating, it is not easy to implement effective and sustainable electric heating. The main problems include: [0003] 1. The planning, design and construction of the centralized electric ...

AI Technical Summary

Problems solved by technology

[0003] 1. The planning, design and construction of the centralized electric heating system takes a long time, and the investment per unit heating area is large, the investment recovery period is long, and the system operation and management cost is high;

[0004] 2. The existing distributed electric heat storage products have high surface temperature, high cost and inconvenient installation;

[0005] 3. Existing distributed direct power supply products use peak power and flat power, resulting in high operating costs and cannot be used for grid load regulation;

[0006] The aforementioned three types of electric heating methods do not have the function of cooling in summer;

[0007] 4. At present, the use of air source heat pumps has become a major clean heating method. This kind of heating equipment can achieve clean heating in winter and cooling in summer, but there are also problems such as high operating costs and no power grid balance capability

[0009] In addition to air-conditioning loads, most other power loads also have obvious timeliness, that is, the peak period of electricity load during the day, and the low period of electricity load at night. Great difficulty, but also a waste of social resources (need to build larger power plants or grid load regulation equipment)
