Adsorption refrigeration device driven by parabolic solar thermal collector and heat pipe

Abstract

The invention discloses an adsorption refrigeration device driven by a parabolic solar thermal collector and a heat pipe, which comprises a condensing circulation loop formed by connecting an adsorbent bed, a condenser, an ammoniacal liquor storage device and an evaporator sequentially, the parabolic solar thermal collector and the high-efficiency heat pipe. The parabolic solar thermal collector carries out heat transfer with the adsorbent bed through the high-efficiency heat pipe. The adsorption refrigeration device converts the solar radiation energy into latent heat of the working fluid by using the high-efficiency parabolic solar thermal collector and the high-efficiency heat and mass transfer heat pipe, heats an adsorbent from the inside of the adsorbent bed to make the adsorbent have better resolving effect; and simultaneously, fins are arranged in a condensing section of the heat pipe so as to strengthen the heat dissipating capacity of the heat pipe and greatly improve the heat transfer efficiency.

Description

technical field [0001] The invention relates to the technical field of solar energy collection equipment, in particular to a parabolic solar heat collector combined with a heat pipe to drive an adsorption refrigeration device. Background technique [0002] In addition to the general adsorption refrigeration cycle, the solar adsorption refrigeration system cannot be continuously refrigerated, the heat and mass transfer performance of the adsorption bed is poor, the time required for adsorption and desorption is long, the cycle period is long, the system adjustment lag time is long, the refrigeration power is small, and the refrigeration coefficient is small. In addition to the disadvantages of low energy utilization rate, there are two unique defects: First, the solar adsorption refrigeration cycle generally cannot be continuously refrigerated, and the cycle period is very long, generally up to 24 hours, and the cooling at night does not conform to the law of energy consumptio...
