Description

There are several types of refrigeration machines that use direct heat energy to generate cold.

Of these, steam jet and absorption chillers of various modifications were recognized and spread.

At the same time, a rather high potential heat is required for absorption machines, while steam engines need heat of even greater potential.

The proposed refrigeration unit allows utilizing and using heat of lower potential, available in many areas of the national economy, in particular in the chemical and food industries, as a waste product, and using a mutually insoluble liquid mixture composed of two components: low-boiling refrigeration agent and high boiling fluid ejector working substance. In addition, the refrigeration unit is easy to manufacture and operate.

A distinctive feature of the design of the refrigeration unit is the use of the well-known evaporation-dependent vapors dependent on each other and successively attached to its upper part in the zone of boiling refrigerant of a reflux condenser, a condenser regulating in; A 1 or expansion cylinder, an evaporator or cooling batteries for separating a coolant; low boiling agent in a vapor state, liquefying and subsequent evaporation (cold) from a mutually insoluble liquid mixture.

For suctioning vapor from the evaporator and returning the vapor-liquid mixture of the refrigerant and working substance formed in the ejector to the evaporator, a pump, a heater and a hydraulic ejector are connected in series to the lower part in the liquid zone of the high-boiling working substance.

The refrigeration unit shown schematically in the drawing contains an evaporator / heated by a low-potential coolant, successively connected to its upper part in the zone of boiling refrigerant and connected to each other by a reflux condenser 2, a condenser 3, a control valve or an expansion cylinder 4, an evaporator 5 separations are mutually disaggregated
