Heat pump and water heater and water economizer combined household electrical appliance system according to climatic variation

Abstract

The invention provides a household appliance system which is combined by a heat pump, a heater and a water saver and can respond to a climatic change, which is characterized in that a water saving system is matched with the heater used for heating with two steps so as to recover the condensed heat of the heat pump; the household equipment which forms the whole system is relatively independent on functions and is relatively concentrative on controls. The combined household appliance system mainly has obvious energy-saving effect, thus reducing the requirement of the electric energy and the exhaust of carbon, and restraining the electricity usage peak in summer. The combined household appliance system also has water-saving effect, properly solves a plurality of technical difficult problems that the condensed heat recovery technique is applied to the household appliances, puts forwards and solves the water temperature control problem of the condensed heat recovery technique heater. The technical proposal is suitable for the generalization and application to the household air conditioners and refrigerators of the condensed heat recovery technique on large scale. In aspect of responding to the climatic change, the whole system has dual effects of reducing the greenhouse effect which is caused by the exhaust of carbon and directly reducing the temperature of the atmosphere close to the ground in summer. During batch application, the combined household appliance system practically provides a method used for artificially controlling the temperature of the atmosphere close to the ground.

Description

technical field [0001] The present invention relates to a household electrical appliance system, especially mainly composed of a domestic condensing heat recovery heat pump device, a domestic water heater and a domestic water-saving system, which mainly has energy-saving effects, thereby reducing electric energy demand and reducing carbon emissions, including water-saving effects , a home appliance system that can directly reduce the temperature of the atmosphere near the ground in summer after extensive use. The household devices that make up the whole system are relatively independent in function and relatively centralized in control. Background technique [0002] At present, the known domestic fully enclosed water storage type electric water heater mainly consists of a shell, an insulating layer, a pressure-bearing inner tank, and an electric heating tube. Its working principle is to heat the water stored in the pressure-bearing inner tank by the electric heating tube. ...

AI Technical Summary

Problems solved by technology

[0007] However, in summary, the outdoor unit of the existing household air conditioner directly dissipates heat to the atmosphere, which aggravates the trend of climate warming.

Existing refrigerators directly dissipate heat to the indoor air, which leads to an increase in room temperature and increases the cooling burden of the air conditioner in summer

As for the domestic condensation heat recovery heat pump device, because its structure is much simpler than that of large and medium-sized heat pump devices such as central air conditioners, the existing technical solutions for condensation heat recovery have to pay for the matching problem between the actual cooling water volume and the required cooling water volume. The price is very high. Some technical solutions are difficult to mass-produce due to the large volume of the water heater, the required installation space is large, the heat dissipation area of ​​the water heater shell is large, the temperature of the hot water in the tank is often not high enough, and it is inconvenient to use. The complexity of the system leads to high cost, complicated installation, complicated control, and poor overall saving effect. Some technical solutions do not consider the problem of water volume matching; another heat recovery technical problem is the water temperature control of the water heater. The difficulty of control lies in the requirements of the water heater. The temperature of the water in the insulation tank is raised to the set point, but the heat pump requires that the temperature of the water in the insulation tank should always be low. This problem has not been proposed and solved in the known technical solution of the domestic condensing heat recovery heat pump device.
