Example Embodiment

[0015] Figure 1 shows an embodiment of a heat recovery chiller. The heat recovery chiller consists of a compressor 1, an oil separator 2, a hot water heat exchanger 3, a condenser 4, a throttling device 5, and an evaporator. 6 and connecting pipelines, among which the hot water heat exchanger 3 is connected in series between the oil separator 2 and the condenser 4. The high-temperature refrigerant gas from the oil separator 2 enters the hot water heat exchanger 3, conducts heat exchange with the application water flowing through the heat exchanger 3, is preliminarily cooled and enters the condenser 4; Water is used to absorb the heat of the high-temperature refrigerant and then heat up and output it as domestic or production hot water. The hot water heat exchanger adopts any one of plate type, shell and tube type, and casing type.

[0016] Figure 2 shows another embodiment of the heat recovery type chiller, which is mainly composed of a compressor 1, an oil separator 2, a hot...

Abstract

It relates to a heat return cooling machine set. It adds a hot water heat exchanger for heat recovery, with reduced running cost, and pollution to environment of condensation, avoiding traditional issue of bad separation of oil and gas mixture, with safe and reliable running.

Description

technical field [0001] The invention relates to a heat recovery chiller, which belongs to the technical field of air conditioning. Background technique [0002] As we all know, chillers discharge a large amount of condensation heat through the cooling water system during operation, which increases the ambient temperature of the building and causes serious environmental thermal pollution. Moreover, due to the increase in ambient temperature, the working environment of the chiller has also deteriorated, resulting in a decrease in the COP of the unit and an increase in energy consumption of the air conditioner; for hotels, factories and other places that require a large amount of hot water supply every day, the conventional method is to use boilers to produce Hot water, the annual primary energy consumption of hot water production is very huge, and the emission of combustion exhaust gas causes serious pollution to the environment. Therefore, if the recovery of condensation hea...
