Heat pump set using sea water source

Abstract

The invention discloses a sea water source heat pump machines, the character is: it is a refrigerating and heating circular system by connecting refrigerating compressor, full liquid evaporator, water cooling pipe with pipes, the heater structure of the machines is that the pipe pass is for water, the shell pass is for refrigerant, the heat exchanging device is made from special anti-corrosion material, the sea water enters the heat pump machine directly and exchange heat with the refrigerant, it saves the traditional middle heat exchanging system, reduces the heat conducting temperature difference, upgrades the efficiency of the machine, and reduces the cost.

Description

technical field [0001] The seawater source heat pump unit involved in the present invention is a device that directly uses seawater as a cold and heat source for refrigeration / heating. Background technique [0002] Due to the serious corrosion of seawater on ferrous and non-ferrous metals, seawater energy is rarely used in the traditional refrigeration and air-conditioning field. At present, there is no seawater source cooling water (heat pump) unit. If you want to use seawater as a cold and heat source, you need to add a set of intermediate heat exchangers for secondary heat exchange (see Figure 4 ), this method has the following disadvantages: [0003] 1. The cost of the air conditioning system has been increased: expensive corrosion-resistant heat exchangers (such as: titanium alloy plate heat exchangers) and intermediate circulation systems need to be added; [0004] 2. Increased system operating costs: due to the power consumption of the secondary circulating water pu...

Problems solved by technology

[0003] 1. The cost of the air conditioning system has been increased: expensive corrosion-resistant heat exchangers (such as: titanium alloy plate heat exchangers) and intermediate circulation systems need to be added;

[0004] 2. Increased system operating costs: due to the power consumption of the secondary circulating water pump, the operating efficiency of the unit decreases and the production cost increases;

[0005] 3. It cannot be used when the seawater temperature is low
