Abstract

The utility model relates to a water source heat pump device for recovering refrigerating and condensing residue heat. Cooling water in an ammonia condenser for ammonia refrigeration is connected witha cooling water outlet of an evaporator of the water source heat pump. A condenser of the water source heat pump, an evaporator of the water source heat pump, a condenser of the water source heat pump, and a throttle valve form a circulation system of the water source heat pump. A circulation hot water inlet and a circulation hot water outlet of the condenser of the water source heat pump are connected with a tail-end heat exchange device. By utilizing the water source heat pump technical principle, the low-quality energy consumption heat generated in the compressing process of ammonia refrigeration is recovered, the low-quality energy of the original water lower than 30 DEG C is converted into high-quality energy water of 50 to 80 DEG C. The energy can be directly applied to industrial water and industrial boiler water supply of enterprises, and also can be used for heating and bathing systems of enterprises and residents, thereby realizing production ratio of 1:4 to 1:5, greatly preserving energy, and reducing emission of sulfur dioxide and greenhouse gases. As the inlet temperature of the cooling medium of the condenser is decreased, the ammonia refrigerating system can work under low refrigerating pressure, and the refrigerating system is economic and reasonable to run.

Description

Reclaim the headwaters heat pump of refrigeration condensation waste heat
Technical field
The utility model relates to a kind of heat-transfer equipment of process of refrigerastion, relates to a kind of employing water resource heat pump heat-exchange device specifically.
Background technology
As everyone knows, though conventional ammonia refrigeration system is had relatively high expectations,, still be used for systems such as industrial refrigeration, food cold working, central air-conditioning refrigeration in a large number on safety because its cost advantages low and others are not also replaced by novel cold-producing medium.
In traditional ammonia refrigeration system, refrigerant gas ammonia is sucked by compressor, enter condenser behind the compressed one-tenth liquid, in condenser, carry out heat exchange with the cooling medium (water) that continued to flow, make the liquefied ammonia cooling, cooling medium carries out the heat of heat exchange basically by forcing cooling to be dispersed in the atmosphere in condenser.And scattering and disappearing of this heat can not reach desirable effect, especially in summer, because the raising of environment temperature, cause the temperature of circulating cooling medium constantly to raise, the temperature and pressure of condensation is also raising, thereby increases the power consumption of compressor, increases the pressure of refrigeration system.
Summary of the invention
At the defective that existing ammonia refrigeration exists, the utility model is a kind of reduction refrigeration machine coolant temperature and the recycling water source heat pump system of waste heat.
Solving the problems of the technologies described above the concrete technical measures of being taked is: a kind of headwaters heat pump that reclaims refrigeration condensation waste heat, it is characterized in that: connect the import (12) of the cooling circulating water of water source heat pump evaporator (6) at the cool cycles water out (9) of the cold liquid ammonia condenser (2) of ammonia refrigeration, the outlet of cooling circulating water (11) connects the cool cycles water inlet (10) of ammonia condenser, the cold-producing medium circulation pipe outlet (13) of water source heat pump evaporator (6) connects water resource heat pump compressor (5) cold-producing medium feed tube, water resource heat pump compressor (5) cold-producing medium drain pipe connects water resource heat pump condenser (8) cold-producing medium feed tube, water resource heat pump condenser (8) cold-producing medium drain pipe connects choke valve (7) import, the choke valve outlet connects the cold-producing medium circulation pipe import of water source heat pump evaporator (6), the circulating hot water outlet (17) of water resource heat pump condenser (8) connects terminal heat-exchanger rig circulating hot water pipe import, and terminal heat-exchanger rig circulating hot water pipe exports the circulating hot water import (18) that connects water resource heat pump condenser (8).
The beneficial effects of the utility model: utilize the water source heat pump technology principle, the low-quality energy that produces in heat that ammonia compression process in the ammonia refrigeration system is produced and the condensation ammonia process reclaims, thereby makes original about 30 ℃ low-quality energy warm water become 50~80 ℃ high-quality energy hot water.This energy can be directly used in the water for industrial use and the Industrial Boiler water of enterprise, also can be used for the heating and the bath system of enterprise and dwelling house, can realize output than 1: 4~5, reduces the discharging of sulfur dioxide and greenhouse gases greatly energy savings the time.
Owing to reduce the inlet temperature of condenser cooling medium, ammonia refrigeration system is worked under lower condensing pressure, guarantee refrigeration system economical rationality operation.Meanwhile, to greatest extent cooling medium in the ammonia refrigeration system is carried out the whole recyclings of heat of heat exchange in condenser, realize energy-saving and emission-reduction, reduce greenhouse effects, contribute for mitigation of global climate warms.
