Benefits of technology

The present invention is a heat pump system that integrates solar and heat recovery systems for efficient energy usage. The system has a heat recovery exchanger and a solar heat exchanger that work together to provide hot water for household use and supplement the heat pump system, making it more energy efficient. The system also includes a buffer water tank for storing energy from the heat pump and a solar panel for providing additional heat and electricity to the building. The whole house solar power and heating integrated system provides a whole house solution for energy usage.

Problems solved by technology

This process only consumes a small amount of power in comparing to the power required to heat or cool a place with pure electricity.
Commercial systems, however, still suffer from less than ideal performance, measured by coefficient of performance (COP).
Further, as the heat pump extracts heat from outdoor air, moisture in the air may condense and possibly freeze on the outdoor coil.
In extreme cold weather, for example, around −18° C., the COP of a heat pump will approach 1, which is less advantage than a simple electric based heater, thus it is not a commercially viable option.

exemplary embodiment i

An Exemplary Embodiment I

[0023]By way of example, FIG. 2 shows an exemplary heat pump system using the principle aforementioned. According to one aspect of the present invention, the exemplary system (120), as shown in FIG. 2, comprises a heat pump control subsystem (103), a solar heating subsystem (100), anti-freeze circulation pipes (106-113, 130, 131), a domestic hot water tank (102), a buffer water tank (104), an indoor fan coil subsystem (105) and optionally a wall-mounted heat pump (101). The heat pump control subsystem (103) is connected with a solar panel (100) that provides supplemental heat energy to the heat pump, making it more efficient. The heat pump control subsystem (103) also connects with the buffer water tank (104) that stores heated (in the heating mode) or cooled (in the cooling mode) water, to be ready to provide heating or cooling to the house on demand. Further, the heat pump control subsystem (103) connects to the indoor fan coil subsystem (105) that ventila...

An Exemplary Embodiment II

[0041]By way of example, FIG. 3 shows another exemplary heat pump system according to one aspect of the present invention. With reference to FIG. 3, a whole house solar power and heating system is integrated.

[0042]The use of solar energy can be divided into four categories, including light to heat (thermal use), light to electricity, light to chemical utilization, and light to bio-utilization. In these four types of solar energy uses, light to thermal conversion technology is the most mature, and many products are made at relatively low cost. For example, solar water heaters, solar water boilers, solar dryers, solar cookers, solar greenhouse, solar house, solar desalination unit and solar heating and are seen in commercial use. Within this category, perhaps solar water heaters have the most extensive use due to their mature technologies and economy. The solar light to heat system mainly converts collected solar radiation into heat. A typical solar collectio...

Abstract

The present invention discloses a solar heating and cooling central air-conditioning with a heat recovery system. The system includes a solar heating subsystem for providing supplementary energy to a heat pump, a buffer water tank for storing and minimizing energy loss, a domestic water heater for recovering unused heat, and an air handler ventilation and exchanger subsystem. All parts of the system are connected by antifreeze circulation pipes. The present invention combines the solar technology with the heat pump technology, making it work in extreme cold climate. The system is high energy efficient, versatile, safe, reliable, intelligent and flexible in installation.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 61 / 771,547, filed on Mar. 1, 2013, which is hereby incorporated by reference.FIELD OF THE INVENTION[0002]The present invention relates to heat pump for providing heating and central air conditioning, and specifically relates to solar heating and central air conditioning with heat recovery system.BACKGROUND OF THE INVENTION[0003]Heat pumps are commonly used as heating ventilation and air conditioning (HVAC) or heating and cooling systems. A heat pump works as a two-way system, in either heating or cooling mode. It uses the principles of reversed Carnot cycles, and uses a working medium to transfer the energy stored in the environment from outdoor to indoor. This process only consumes a small amount of power in comparing to the power required to heat or cool a place with pure electricity. Therefore, heat pump technology can save a lot of “high-grade” energy, e.g. e...
