Constant-temperature controlled absorption type refrigerating device

Abstract

The invention discloses a constant-temperature controlled absorption type refrigerating device which comprises a first vacuum cavity, a second vacuum cavity, a third vacuum cavity and a water route structure, wherein the first vacuum cavity is internally provided with a first adsorbent bed, a first condenser and a first evaporator; the second vacuum cavity is internally provided with a second adsorbent bed, a second condenser and a second evaporator; and the third vacuum cavity is internally provided with a third evaporator. The water route structure is used for guiding hot water into the first adsorbent bed and guiding cold water into the second adsorbent bed or guiding the cold water to the first adsorbent bed and the hot water into the second adsorbent bed simultaneously for refrigerating. By means of sensing an outside temperature or temperature of ice water produced by the absorption type refrigerating device, the cold water is properly stopped being guided into the second adsorbent bed or first adsorbent bed, so that refrigeration is temporarily stopped and efficacy of constant-temperature control is achieved.

Description

Technical field [0001] The invention relates to an adsorption refrigeration device, in particular to an adsorption refrigeration device with a constant temperature control function. Background technique [0002] With the development and progress of the economy, the demand for energy is also increasing. However, how to develop green energy that does not cause pollution to the environment is the focus of the world’s current attention on the premise of maintaining the environmental ecology. [0003] Among them, adsorption refrigeration technology is especially one of the effective key technologies that can take into account both energy and environmental protection. The adsorption refrigeration device is mainly composed of an adsorption bed and an evaporative condenser, and at least two adsorption beds are required to alternately perform adsorption and desorption to maintain continuous air conditioning capacity. [0004] However, when the adsorption refrigeration device is continuously ...

AI Technical Summary

Problems solved by technology

[0007] The main purpose of the present invention is to overcome the defects existing in the existing adsorption refrigeration device, and provide a new type of adsorption refrigeration device with constant temperature control. The technical problem to be solved is to make it detect the external temperature or adsorb The temperature of the ice water produced by the adsorption refrigeration device, and when the temperature of the ice water is lower than the preset temperature, the refrigeration will be suspended, so as to solve the problem that the temperature of the ice water produced by the adsorption refrigeration device cannot be stably controlled, and then achieve the effect of constant temperature control , very suitable for practical
