Abstract

The present invention relates to a heat recovery type solar jetting electrically-compressing heat pump air-conditioning unit for using solar energy to provide heat and cold. The unit comprises a solar energy hot water circuit, a jetting refrigerant circuit, an electrically-compressing refrigerant circuit and an air-conditioning water circuit. The unit determines the starting and stopping of a electrically-compressing heat pump air-conditioning system according to the need of the load of an air-conditioner and the specific condition of solar radiation, and controls the flow of a water system and the refrigerant through the shifting of valves and switches. Part heat of the refrigerant in part exhaust gas of the compressor can be recycled for heating hot water when the electrically-compressing heat pump air-conditioning system provides cold, and the system is capable of stably and reliably providing refrigeration water for the air-conditioner and hot water with the temperature between 40and 80 DEG C for the air-conditioner. The temperature span of the hot water is large, and the unit satisfies domestic hot water supply, and also satisfies production process heat supply and small area heat supply. The unit is further capable of separately providing low temperature refrigeration water, and is suitable for radiation cold supply and fan coil air-conditioning systems. The unit is capable of sufficiently using solar energy resources, improving solar energy utilization ratio, reducing environmental pollution and relieving the pressure of power network.

Description

technical field [0001] The invention relates to a heat recovery type solar jet electric compression heat pump air conditioner unit which utilizes solar energy for heating and cooling, and is suitable for 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 ...
