Description

I

The invention relates to the chlodion technique, namely to a device for the integrated production of heat and cold, used mainly in agriculture in the lines of personal processing of milk on farms or pastures.

The purpose of the invention is to enhance the functionality by ensuring that water of different temperatures is obtained.

The drawing shows the scheme of the proposed heat pump.

The heat pump contains a circulating refrigerant circuit in which compressor 1 is installed in series, a heater (condenser) 2, a condenser 3, a three-cavity heat exchanger 4 whose cavities are arranged coaxially, a control valve 5 and an evaporator 6. Moreover, to condenser 3 water circulating system connected

heat exchanger 7, cooling tower 8 with tanko 9 for water and pump 10. And to the preheater 2 are connected highways M 1 and 12 for the supply and discharge of running water. The main line 11 after the water heat exchanger 7 is equipped with a valve 13 and is connected to the supply line of the circulating water supply system through a stop valve 14 via a line 15 equipped with a device for supplying warm water to the consumer.

The heat pump works as follows.

From iKOMnpeccopai 1, the compressed refrigerant vapor enters the preheater 2, where it is cooled by heat exchange with running water, and then into the condenser 3, where it is condensed by heat exchange with reverse water. Liquid refrigerant enters the cavity of the heat exchanger 4, where it is supercooled due to heat exchange with 6 pairs entering the external cavity from the evaporator.

coolant and additionally - with running water, flow into the internal cavity. The supercooled refrigerant through the control valve 5 enters the evaporator 6, where it boils, extracting heat from the coolant, pos. Now the heat exchanger 4 is again sucked in by the compressor 1.

Coolant, such as water, circulates in a closed circuit between the cold consumer and the evaporator 6.

Flow water flows from the water supply or pre-cooling section of the product into the internal cavity of the heat exchanger 4, where it is heated by heat exchange with a liquid refrigerant.

The water after the heat exchanger 4 enters the heat exchanger 7, where it is heated by heat exchange with circulating water coming from the condenser 3. After the heat exchanger 7, the water (or part of it through the valve 14 enters the pipeline to the consumer, for example, into the milking unit where sanitization of animals during milking period. Some of the water through the system of the cooling tower 8 feed is supplied to the tank 9. Part of the water or all the water after the heat exchanger 7 can be supplied through the valve 13 to the heater 2. The ratio of warm (after the heat exchanger) and hot (after the preheater 2J water can be changed using valves 13 and 14.

The circulating water is supplied by the pump 10 to the condenser 3, where it is heated due to the heat of condensation through the heat exchange 7, where it transfers part of the heat to the running water, enters the cooling tower8. Due to the heat and mass exchange of water with the surrounding air in the cooling tower 8, the circulating water is cooled, the cooled water is again supplied to the condenser 3, and the cycle is repeated.
