Heating and cooling system utilizing a water source heat pump and a swimming pool

摘要

A heating and cooling system includes a swimming pool, a pump connected to the swimming pool, a pool cooler connected to the pump so as to cool water passing from the pump, a water source heat pump cooperative with the pump so as to receive water as passed by the outlet pipe of the pump, a valve mechanism connected to the outlet of the pump so as to control the flow of water toward the pool cooler and the water source heat pump, and a pressure control valve cooperative between the valve mechanism in the inlet line of the pool cooler so as to limit a pressure of the water flowing from the valve mechanism toward the inlet line of the pool cooler. A pressure control is connected to the outlet line of the pool cooler so as to reduce a pressure of the water flowing from the outlet line to the pump.

1. A heating and cooling system comprising:
a swimming pool having water therein; a pump in fluid communication with the water in said swimming pool, said pump suitable for drawing water from said swimming pool therethrough, said pump having an inlet pipe and an outlet pipe connected thereto; a pool cooler suitable for cooling water passing therethrough, said pool cooler having an inlet line and an outlet line connected thereto, said outlet line communicating with said inlet pipe of said pump, said outlet line having a pressure control thereon so as to reduce a pressure of the water flowing from said outlet line to said inlet line of said pump, said inlet line having a pressure valve thereon so as to reduce a pressure of the water flow to between 4 and 6 p.s.i.g.; a water source heat pump cooperative with said pump so as to receive water as passed by said outlet pipe of said pump, said water source heat pump having a first line and a second line extending therefrom, said first line having a modulating valve thereon so as to control a flow of the water to said water source heat pump, said water source heat pump having a condenser and an evaporator and a compressor with a reversing valve cooperative therewith; a valve mechanism connected to said outlet of said pump so as to control the flow of water toward said pool cooler and to said water source heat pump; and a pressure control valve cooperative between said valve mechanism and said inlet line of said pool cooler so as to limit a pressure of the water flowing from said valve mechanism toward said inlet line of said pool cooler to a pressure of between 8 and 10 p.s.i.g. and to assure that at least 2 p.s.i.g. of water flows from said valve mechanism to said water source heat pump, said pressure control of said outlet line of said pool cooler limiting a pressure of the water flow from said pool cooler to said pump to between 0.25 p.s.i.g. and 0.50 p.s.i.g.
