Embodiment Construction

[0027] The present invention utilizes the combination of solar water heating system and VM cycle heat pump technology to achieve the purpose of the present invention. In summer, when air conditioning is required for cooling, solar energy can be used as the driving energy to drive the VM cycle heat pump to work for cooling. In other seasons, as long as there is sunlight , can also make full use of these energies.

[0028] Such as figure 1 As shown, the whole system is composed of VM cycle heat pump system and solar water heating system. The VM cycle heat pump system consists of a cold cylinder 1, a cold push piston 2, a cold regenerator 3, a hot cylinder 4, a hot push piston 5, a hot regenerator 6, a cold heat exchanger 7, a cooler 8, a room temperature cavity 23 and The drive link mechanism 9 for pushing the piston and the drive motor 18 are formed. A heat source heat exchanger 10 is arranged between the hot cylinder 4 and the heat regenerator 6, and forms a circulation loop ...

Abstract

The invention discloses a solar-powered VM circulating heat pump system, which comprises a VM circulating heat pump system, a solar water heating system, a heat supply circuit and a cold energy supply circuit, wherein a heat source heat exchanger is arranged between a hot cylinder and a heat regenerator in the circulating heat pump system; the heat source heat exchanger and a water container in the solar water heating system form a heat exchange circulating system; and the energy transfer between the two systems is completed. When the system is used, solar can be used as driving energy to drive a VM circulating heat pump to work to cool or heat in order to meet an air conditioner cooling requirement. The solar is clean, safe and reliable, so energy shortage and environmental pollution are prevented. The system can be widely used in industrial, commercial and civil concentrated cooling and heating systems.

Description

technical field [0001] The invention relates to a VM cycle heat pump, in particular to a VM cycle heat pump using solar energy as a driving energy, and belongs to the technical field of heat pumps. Background technique [0002] As a clean and renewable energy, solar energy can be developed and utilized locally. It is inexhaustible, inexhaustible, and will not pollute the environment and destroy the ecological balance. The solar radiant energy reaching the earth's surface every day is 5.57×10 18 MJ, equivalent to 190 trillion tons of standard coal, is about 1.56×10 of the current total primary energy consumption in the world 4 times. There are two main ways to use solar energy as the driving energy of heat pumps. One is to realize light-to-electricity conversion, and then use electricity to drive conventional compression heat pump units; the other is to perform light-to-heat conversion and use heat as the driving energy. The former system is relatively simple, but high-pow...
