Abstract
Air-cooled water-cooled double-evaporator hot water unit. The invention relates to an air-cooled water-cooled double-evaporator hot water unit for recovering waste water waste heat. The refrigerating circulation loop consists of compressor, water cooled condenser, air cooled evaporator and water cooled evaporator, and the refrigerant in the loop is switched via controller. The present invention has two heat source sides-a water source and an air source. The invention can save a large amount of energy in application, and has low equipment cost and good performance.
Description
Technical field
The present invention relates to the association system of a kind of heat supply, heat supply simultaneously, cooling, relate in particular to a kind of air-cooled water-cooled two-evaporimeter hot-water machine group that reclaims waste water residual heat.
Background technology
At present, a lot of bathing places have a large amount of hot water with uniform temperature to discharge as sewage, and these water do not possess the value of recycling from the health angle, but its heat that contains has the value of utilizing again.Especially in the winter time, the temperature of the water of these discharges reaches 30 ℃, makes full use of this heat energy savings greatly, reduces cost.
Summary of the invention
The purpose of this invention is to provide a kind of two heat source side that have been connected in series, the air-cooled water-cooled two-evaporimeter hot-water machine group that one of them heat source side can heat the heat absorption among the spent hot water.
Technical scheme of the present invention is: it has one by compressor, water cooled condenser, air-cooled evaporimeter, the refrigeration cycle that the water-cooled evaporimeter is formed, cold-producing medium in this loop switches by controller, compressor connects water cooled condenser by a cross valve, be connected with on the water cooled condenser into, delivery port, a pipeline in parallel with water cooled condenser, be provided with check valve in the pipeline, water cooled condenser connects the water-cooled evaporimeter, be connected with heating power expansion valve between the two, the water-cooled evaporimeter is provided with into, delivery port, a defrost pipeline in parallel with the water-cooled evaporimeter, the water-cooled evaporimeter connects air-cooled evaporimeter by a check valve, air-cooled evaporimeter connects cross valve, and cross valve connects the refrigerant-cycle systems of compressor.
Be respectively equipped with temperature sensor at each entery and delivery port, temperature sensor connects controller.
Be respectively equipped with heat-exchanger pump at each water inlet.
Be respectively equipped with magnetic valve on the pipeline of the inlet of water-cooled evaporimeter and on the defrost pipeline in parallel with it, magnetic valve connects controller.
Double evaporators unit of the present invention has two heat source side-water sources and air source.The water-cooled evaporimeter at water source-water source is provided with the entery and delivery port at water source, utilizes the water-cooled evaporimeter to absorb heat energy in the waste water, again by water cooled condenser with this thermal power transfer in refrigerant medium, be transformed among the domestic hot-water by condenser again.Thereby reach the purpose of domestic hot-water supply, during summer while, the water-in and water-out of water-cooled evaporimeter are connected to interior conduit, thereby reach purpose to indoor cooling; The air source-for preventing waste water heat supply deficiency, in refrigeration cycle of the present invention, be serially connected with an air-cooled evaporimeter with the water-cooled evaporimeter, can promote heating effect more on the one hand, under the situation of waste water shortage of heat, from air, absorb heat with air-cooled evaporimeter and carry out complementary heating in addition.When air-cooled evaporimeter and water-cooled evaporimeter adopt series system, during the unit defrost, directly between two evaporimeters, move by check valve and defrost capillary, make water cooled condenser not drop into defrost operation, the thermal losses in the time of can reducing the unit defrost by another check valve.The present invention can save a large amount of energy in application, equipment cost is low, and performance is good.
