Abstract

The invention relates to a solar jet electric-compression combination-type heat pump air-conditioning set, which supplies heat and cold energy through solar energy. The air-conditioning set consists of a solar collector system, a jet cooling system, an electric-compression heat pump air-conditioning system, a water container, a water distributor, a valve and a piping system. Based on the prior solar jet type cooling systems, an electric heat pump compressed air-conditioning system and a necessary pump are provided; the jet system and the electric-compression heat pump air-conditioning system are started up or shut down according to the air-conditioning load and the radiation of the sun; the valve is used to control the flow of the water system to supply heat energy and cold energy to air-conditioning users through the set, which solves the problem of unbalance between the solar energy source and the air-conditioning load in the process of heat / cold energy supply, and reliably and stably supplies air-conditioning with cooling water and heating water, wherein the temperature of the heating water is between 40 degrees centigrade and 80 degrees centigrade; the temperature range of the water is wide, therefore the solar energy is fully used and the utilization ratio of the solar energy is increased. Besides, environmental pollution is reduced, and the pressure on the grid is relieved.

Description

Technical field: [0001] The invention relates to a solar jet electric compression composite heat pump air conditioner unit for heating and cooling by solar energy in the field of air conditioning and refrigeration. Background technique: [0002] With the further aggravation of the energy crisis, the utilization of solar energy has become the focus of attention. In the solar energy utilization technology, the solar jet refrigeration system is favored by everyone for its simple structure, few moving parts, and low cost, and it is more and more widely used in the field of air conditioning and refrigeration. The operation effect of the traditional solar jet refrigeration system is mainly restricted by two factors: one is the variation of solar radiation intensity, and the other factor is the variation characteristics of the cooling load of the air conditioner at the user end. The collection of solar energy can only be carried out during the day when the sun is shining. Usually,...
