Novel one-driving-two freezing, refrigerating and drying system

Abstract

The invention provides a novel one-driving-two freezing, refrigerating and drying system. According to the novel one-driving-two freezing and refrigerating drying system, the requirements of a freezing warehouse and a refrigerating warehouse are met through one set of system, defrosting is fast, energy consumption is low, heat pump drying is taken into account, and a heat pump drying function can be provided for places with drying requirements. A first warehouse heat exchanger is arranged in a first warehouse, a second warehouse heat exchanger is arranged in a second warehouse, an air outlet of a compressor is connected with an oil separator, the air output end of the oil separator is connected with a port D of a first four-way valve, a port C of the first four-way valve is connected to a first medium port of an outdoor heat exchanger, a second medium port of the outdoor heat exchanger is connected with a first port of a liquid storage device, a second port of the liquid storage device is connected to a port D of a second four-way valve in parallel and a port D of a third four-way valve, a port C of the second four-way valve is connected with a first expansion valve and then connected with a first port of the first warehouse heat exchanger, a second port of the first warehouse heat exchanger communicates to a port E of the second four-way valve, and a port S of the second four-way valve is connected to a port E of the first four-way valve through a pipeline.

Description

technical field [0001] The invention relates to the technical field of sludge drying equipment, in particular to a novel one-drag-two freezing and refrigerating drying system. Background technique [0002] Now there are more and more community-based fruit and vegetable supermarkets. Some items need to be refrigerated and others need to be frozen, but the storage volume is very small. Using existing products, a set of refrigeration equipment corresponds to a storage volume, which is uneconomical and consumes a lot of energy. , and most of the small-scale refrigeration equipment now adopts the form of thermal expansion valve electric defrosting, which has a long defrosting cycle, high storage temperature rise, and high energy consumption. Contents of the invention [0003] In view of the above problems, the present invention provides a new type of one-to-two freezer and freezer drying system, which solves the needs of two freezer and freezer warehouses through one system, an...

[0002] Now there are more and more community-based fruit and vegetable supermarkets. Some items need to be refrigerated and others need to be frozen, but the storage volume is very small. Using existing products, a set of refrigeration equipment corresponds to a storage volume, which is uneconomical and consumes a lot of energy. , and most of the small-scale refrigeration equipment now adopts the form of thermal expansion valve electric defrosting, which has a long defrosting cycle, high storage temperature rise, and large energy consumption.
